Ford Aerostar :: 1993 - Bogs Under Acceleration / No Power
Jun 2, 2016
My 1993 ford aerostar 3.0 is a great vehicle but recently its been killing me trying to figure out what the cause is. I'll start at the beginning. I had a job over the hill in Westwood Ca. Ran low on gas on the way home. Too low apparently. Since i refueled it has a really rough idle and no power under acceleration. After it gets warmed up i get a bad smell of gas and exhaust in the cab.
Now if i turn it off wait 15 min or 12 hours it will run ok for 2 min then back to hell. I has not stalled and i have replaced the fuel filter and a few months back i cleaned the Mass air flow sensor and replaced the TPS. I would love to take it to a mechanic but as i have been living in this old girl for the passed 6 months money is non-existent.
What to do. I have even tried disconnecting 1 at a time... the TPS, MAF, and the 02 sensor. No difference. There has been no check engine light until I tested by disconnecting TPS etc.

My 07 F150 has no power. I changed the timing chain, cam phasers, spark plugs and all 8 coils and still no power. Rough idle and bogs on acceleration.

We have a 1993 Ford Aerostar 4wd Eddie Bauer edition. This van has 150,000 miles on it. In the past 2 years we've had a number of problems related to the van idling hard and having a lack of power.
First, the van revved high and low and was unable to maintain a steady idle....I replaced the throttle positioning sensor and this fixed the problem. Next, the van was running sluggish and was very slow to respond when you pushed the accelerator....I replaced the oxygen sensor and it fixed the problem.
Currently, (a few months after changing the oxygen sensor and the problem being temporarily fixed) the van is having the same issue as before I replaced the O2 sensor (running sluggish and slow to respond to the accelerator). If you press the accelerator down (even to the floor) it barely responds, you can get it driving at highways speeds but it takes a long time to baby it up to those speeds.
When you let off the accelerator after pressing the petal down it actually sometimes gets a second of power. It also is not maintaining a stable idle (fluctuating between high and nearly dying). I bought a new 02 sensor and installed it but it didn't fix the problem this time. The exhaust smells rich in gas. What else might make the van run like this? Possible solutions for where to look next?

I just purchased a 93 escort sedan 1.9 ltr engine. Car runs great when idling but bogs down when accelerating to the point it almost stalls out but doesn't stall. the car sat for a while 6 + months. We thought the gas might be bad so we drained the tank filed it with premium to run thru the line but that didn't work. thought maybe o2 sensor, changed that but didn't work. getting error codes 412 and 538 but can't find any info on these codes.

I have a 460 with a holley manual choke 750 single pumper carb on it, when I pull out truck bogs very badly, if I try to punch it will stall unless I let off the throttle.
It seems to run best with choke almost all the way on. What the problem could be?
I'm almost positive its a carburetor problem, just not sure exactly what the problem is, could a blown power valve cause this??
The accelerator pump seems to be working properly ...

We have a question about our 93 Aerostar. The A/C is working, but not very well. Not cold enough. It is fully charged. We are not able to see any condensation dripping below the car when parked, after running the air. We cannot discover where this condensation is going, or even wbere the hose from the evaporator is supposed to be. Shouldn't it be coming down into the front wheel well area? We have had the van since about 03, and the AC system has been replaced in that time. When the weather is cool (not often this summer) the air works OK, but it isn't keeping up in hot weather.

Is it possible to convert a 1993 2WD Aerostar EB with a A4LD to a AWD drivetrain? I am a Subaru veteran (this is my first time posting), and the mod capabilities of soobs is endless - older 2wd car to AWD is not hard at all on those cars - in fact it is a relatively easy bolt-in change.
Traction on snow (or anything else) in a stock 2WD Aerostar leaves MUCH to be desired (especially when compared to a vintage soob). How good is the AWD drivetrain overall? Is it as reliable and rugged as the 2WD? Gas mileage difference between 2wd and AWD? Handling? Maintenance? Are there different versions of the AWD? If so what are they like? I have a 1993 FSM for the drivetrain, but I don't know how similar other model years are.

1993 Golf GL III, automatic: Engine size: 2.0 Date on door 5/1993
I have an intermittent problem, in the morning my car will start fine, idle fine and drive well for about six blocks, but then it suddenly bogs down and goes sluggish like it is not getting gas or not firing correctly. It has not stalled completely, it just bogs down and giving it gas does not do much. I can barely coax the car to my destination about a mile away.
The weird part: A few hours later when I leave this location my car runs fine, starts fine, drives fine and I have no problems the rest of the day. Thus, I only have this problem in the morning, otherwise the car runs great.
Question: Could there be a sensor that is reading incorrectly in the morning, but is fine after it warms up? Perhaps the sensor is messing up the air/gas mixture.
NOTE: My check engine light is on, but I have not figured out how to pull the codes. In the middle console, above the ash tray behind two unused button panels, I have two diagnostic connectors, one black and one white (see photo). I think they may be 2x2 connectors, perhaps OBD1, but I am not sure.
* I have heard a jumper cable can be used to get the codes to blink, but I have not found any documentation to confirm that for this year and model.
* I am also not sure if an OBD2 scanner could read this codes if I use an 16 pin adapter.
Pull codes, either using a jumper or scanner, My local auto parts stores will not pull the codes.

Well I've got an nice steady leak coming from the front of the pan.... running aft of course (downhill, windflow). She's down right now for an AC overhaul and new PS pump/hoses, but I'm inspecting to see what is next to get this stinking oil leakage stopped.
Front HB removal and seal of course, done in situ (in position). But if it is actually the oil pan/seal, can that be done there also? Front of the pan looks tight to the crossmember, and how the internals look (tray baffles, pump pickup) I've no clue if it will come off. Once she is back up and running I'll ascertain where this leak originates.
Interweb searches show the 90-94 4.0L engine is notorious for pan gasket leaks. None of the writeups I've found thus far determine if that pan can be pulled where she sits.

I have a 1993 Chevy Silverado rwd automatic 350 5.7. It died on me on the way to work this morning. It slowly lost power and acceleration. The lights and radio all worked. When I tried to restart, it tried to start but then just cranked like it had no fuel or spark.
I had it towed home and checked the following things. I removed the fuel filter, it is clear. I verified that the fuel pump was working by turn the key to the on position while the filter was off. Good stream of fuel. I verified that there was fuel to the TBI. Good spray while cranking. I verified that there was spark by pulling a plug out, connecting to the wire and cranking the engine. Spark seemed weak but there was spark. The front plugs were dry, but the rear plugs, especially #8 was very wet. I verified the timing by pulling the #1 plug, removing the distributor cap and checked the rotor position. I bumped the engine to get the #1 piston to the top of the cylinder and the rotor was point directly at the #1 plug wire. The cap, rotor, plugs and wires are only 1 month old.
I also tried to check the ignition coil by disconnecting the coil wire from coil, and slid the boot back to expose the contact. I held it just of the coil while the engine was cranked, but did not actually see a spark at the coil. I did not hear any arcing. I pulled another plug and checked for spark. Again i had spark. Just seems weak to me. I am on my way to the auto parts store to get a new coil.

My Aerostar is a 93 extended EB with 4.0, AT, 212k mostly reliable miles, and blue and gold paint that has held up remarkably well. When started it runs great; smooth idle, easy revs, normal as can be. But when that third pip on the digital temp gauge hits Normal the van becomes possessed. The idle will randomly drop or surge or return to normal, the check engine light will come on for a few seconds then go off, all without pattern, just kinda crazy. Today I held it at 2k rpm, then it bogged down to like 800 rpm and lit the CEL, then it returned to 2k rpm and the light cleared, swung up to 2.5k, all while I hold the throttle steady. The light does not always come on when it bogs. I see no black smoke from the exhaust and it smells normal, but it was kinda windy today.
The check engine light is not lit otherwise so I assume no hard codes are stored. I think I found the code retrieval process for the OBDI but I have not done that yet. After reading a bit in this forum I thought to clean the MAP sensor, but I do not have security torx bits to remove it yet. As background a few years ago it had an oil leak from the top rear which I ignored, and it slowly rotted a harness back there till one day the harness died leaving me running on 3 cylinders. My local Speedy Lube guy was ex Ford dealership and knew Aerostars, he did the diagnosis and repair and said it was a common problem. But he has moved on. I was also told I have a torn boot on a plug wire, but there's no way to get my ham-like paws back in there, from front or back, to verify or replace. I mention all this as background, I doubt a bad plug wire is the issue here.
It seems like an odd problem to me because the only pattern is related to operating temp. It is not a constant problem, not an intermittent glitch, but it very definitely goes nuts right when it achieves normal temp. Aside from pulling the codes, which I will figure out tomorrow, any other tests I can run to diagnosis? Any way I can trick this thing into thinking it is cold all the time?

I went to put the van in park, and the gear shifter just went all floppy in my hand. I was able to wiggle/jostle it around and get it into neutral or drive, but nothing else. Tow truck driver crawled under the van, and put it into drive for me, and told me it was probably just going to need a new cable or link shaft (tube shaped thing)... My hubby usually fixes these things, but is now living 1700 miles away.
Anyway, the shop called me and said I needed a new steering column, and said something about the 'lower' cap or half??? He quoted me $340 for the job. I am not getting the connection between the gear shifter being loose/floppy and the steering column needing to be replaced? Is this right?
It is a 1993 Aerostar, 3.0 by the way...

I have a 1993 Aerostar 3.0L, automatic. The transmission has started dropping out of overdrive into drive while at speed. It's very inconsistent as sometimes it will drive without incident and sometimes it will barely go into overdrive and then drop back out and remain in drive for an extend period of time. I changed the fluid/filter/gasket thinking it was just overdue for changing but no luck. The fluid level is fine, perhaps even a little high. Fluid looks clean on the stick, so I don't think it was a lack of draining enough fluid. The problem seems to be more pronounced when warmed up.
Also when cold, I've had an issue with it stalling while taking off from a stop. I wouldn't necessarily relate the two problems, but someone mentioned they thought they might both be a symptom of a slipping torque converter or something. But the stalling issue seems to go away when it's warmed up.
Also had an issue with the van not wanting to start when damp. But I attributed this to water getting on the coil or plugs or something. What I could try before taking it to a shop and risking getting taken?

My '93 has the RABS lite on when I use the brakes and the brake light comes on when I use the brakes hard. While searching the topic I stumbled on a reference to bypassing theRABS with a piece of brake line, Looking for the particulars on this?

'93 2wd, standard instrument panel. Headlights and brake lights work fine. No instrument lights or taillights. The problem, at least with the dash lights, seems to be intermittent. My son has told me the dash lights are out, but they worked when I drove it later. I rarely drive the van. Is this a problem with the headlight switch? I pulled all the fuses, and checked the bulbs in the taillights, and everything looked ok.

My neighbor and son took it upon themselves to get the rear latch to catch... well they have done that..... .and then some. I have got the interior panel removed and the what i will call the latch plate assembly out of the way... I can see one Phillips head screw down in the hole ... but can get nothing to move ... this thing is rock solid on the latch bolt.... what can i do?

My Aerostar lately has been doing some weird things when going around corners. Whenever I'm going around a corner and I give the wheel a good turn the whole front end and the steering wheel start to shudder hard, and it sounds like the engine is being slightly bogged down. As soon as I finish though and straighten out it goes away immediately. Could this be the serpentine belt or the PS?

I recently bought a 1993 Aerostar. When I go to drive it after it rains as soon as I turn the steering wheel a good deal of water comes from the bottom of steering column right into my lap! Why this happens and what I can do to fix it?

My 93 with 210K miles threw a new one at me the other day. Not 1 mile from work with AC running, it started stumbling a bit at around 40MPH. I just assumed it was the AC cycling and the Van was in OD. Dropped into D and drove her on home.
Well this morning was round 2.... got about 2 miles from home and it started stumbling again (no AC this time). Just happened to look down at my digital dash and the speed was jumping all over, finally settling on 0 MPH. I got about a mile down the interstate and it suddenly reactivated and displayed 70mph.... smooth as silk.
OK, so I know that the rear diff. has a sensor for ABS, and obviously a pulse wheel on the diff. Is this sensor the input for speed? From other makes, I understand the pulse train input is "conditioned" in another device ( hardware) which then outputs to the dash display.
Based on these assumptions, I'm going to assume the crazy speed variation was playing hell with the ECU. When it settled on 0 mph it was happy again. Can't just be a display issue as there would have been no stumble. Getting ready to drive her about 3.5 hours this weekend to go trout fishing.... obviously the cruise won't work but otherwise it appears to function WITHOUT the speed input.

Have a '93 Aerostar that had something roll up against inside sliding side door and must have nudged it out of alignment. Broke off outside door handle, took off inside panel and tried prying, pushing, kicking and pulling rods, handle, linkage and anything I could get at. Any way to get it open, so I can re-align the catch mechanism??? I have tried everything I could to "muscle it" open....

I have a 97 Pontiac Grand Am w 3.1 engine that is my son's college car. We recently rebuilt the original engine and put it in after having a 99 monte carlo 3.1 engine in it's place and it had a head gasket problem as well. Just before we switched engines my son was noticing that it would kind of hesitate under acceleration from about 1500 rpm to around 2000 rpm especially when it was wanting to up shift. I figured it would resolve itself with the engine change. It did not. It has now gradually gotten worse.
My son drove it to Liberal about 4 hours away and he stated it was worse and especially when you would get into overdrive it would drop down to around 2000 rpm then start sputtering or loading up or just being dead then would down shift to 3rd and try to clean itself out and speed up and then up shift to OD and do the same cycle again. I drove it back and kept it in 3rd gear and seemed to run fine at 2500 or higher. I also had to go thru low, and 2 and feather it up from a standing start. It idles fine as well.
I thought it might be like one of the saturns I had which ended up having a plugged Catalytic converter and a bad coolant temp sensor. This morning I did a test hole and it made no difference. I tried a different coil pack/ESC and it made no difference. I cleaned the MAF sensor and no change. The fuel pressure is 41 then 38 when idling then 43 when remove the fuel pressure regulator vacuum hose. I also changed the fuel filter.
I was kind of ruling out the tps, iac, and egr and water temp sensor as those were part of the other engine when I put the other engine in so they are different and I am assuming they must be good. Plugs and plug wires are new as well. It has not thrown any codes. I did notice that when it is just in park and you press on the accelerator to rev it up it only will rev to 3500 rpm and will shut down like a rev limiter is kicking in and just do a kind of surge thing. My saturn did that too and it was a plugged cat and when I knocked the biskit out of the manifold on that car it stopped. I have already got that ruled out though.
