Ford - Explorer - Transmissions :: 1998 - Engine Surges At Constant 2500 RPM
Aug 4, 2011
I have a 98 ford Explorer that has some serious trans problems. It all started a while back when I was pulling a small 10 foot trailer and when I go to where I was going the trans puked out what looked like all of its internal fluids. It was a hot day, and these problems seem to be exacerbated by the heat but who knows. Yes the check engine light is on. I also have the occasional O/D OFF light blinking at me. As of late the vehicle has started to act like it has a stall converter on it. I have to rev to nearly 3k RPM before it will engage.
I changed the fluid and filter about 2 months ago and the fluid is already grey and nasty. The vehicle has also started going FORWARD in ALL gears, Reverse, Neutral, etc. all are forward gears now. The trans occasionally overheats and pukes out a large amount of fluid but I cannot tell where it is coming from. At road speed (55 MPH) the engine surges when it is at a constant 2500 RPM. I know my outlook is grim but if I just need a new torque converter I would like to know before I go the the Salvage yard for a different transmission. BTW. The engine WAS replaced around 12,000 miles ago with a donor engine from a flipped vehicle.

This engine unexpectedly surges from idle up to as much as 3 or 4 thousand RPM. It can be frightening. The IAC valve was buzzing loudly so we changed it out a couple of times with wreckers parts. With the third replacement valve in there, it hasn't surged yet but we are very leery to drive it for fear of uncontrolled acceleration while in heavy traffic. Is this a known problem or recall with these vehicles. I think it is ridiculous that the design would allow such a dangerous condition!

We have a 2003 Passat GLX, 43000 miles, V6, AWD. I've noticed recently that when driving at constant speed the engine will surge about once every second or two. It's very regular, and on a smooth road I can also notice a bump in the drive train, very similar to road bumps.
I've taken it to a dealer, since I believe it is a transmission issue, and therefor covered under warranty. There are no computer codes stored for faults in the transmission, they've said. However, they started by pursuing the fuel injection system (though no code was stored), and then wanted to fix a faulty coolant sensor (since found not to be faulty).

1992 Fod Explorer XLT: When I attempt to turn over the engine, the flywheel spins, but the engine doesn't. This is a very gently driven vehicle. I drove home hone day, backed into the driveway and unloaded the groceries. The next morning, when I tried to start it, the engine will not turn over. I dropped the starter and tested it--all good. While I had the starter off, I found I could spin the flywheel freely--appears to not be attached to the engine. It's tight with no play whatsoever. Last year I had a new flywheel installed--something I would do myself, but decided I'm at the age, I'm just not up for it. It's been running great for 18 months with no problems. There was never a noise. This just happened one morning. I thought the crank may be broken, but that seems unlikely since it was driving great until the next morning.

I purchased my first Ford back in 2006 it was a 1999 Explorer Sport. Gave me a long line of problems from suspension to head gasket repair to rear main seal repair to ANOTHER head gasket repair. But sure enough, like I'm sure many of you have, I fell in love with her. She could do no wrong. Even now that I got her off the road she is still my baby. Now my recently purchased 2000 Explorer XLS which I've only had for about 5 months just yesterday started doing a strange hesitation. Perhaps a misfire. My initial instinct was dirty fuel injectors that hopefully if I'm lucky will be the easiest fix in Ford history. Another hypothesis is a bad plug. Either way, in my mind, that's best case scenario. I have yet to take it in and plan on buying some injector cleaner later on today. When I'm idling there's no problem. It's as soon I step on the gas that I feel the hesitation. Almost like a constant hiccup.

I have a 2012 Camry LE. When I let off the gas between 25 & 40 mph, the transmission aggressively brakes. Occasional acceleration surges when braking. And when I need to go, it sometimes does not want to go until I punch it. All problems are sporadic.

I have a 1997 explorer sport 4x4 4.0 sohc It has a real tuff time with cold starts sputters won't hold and idle sits at about 500 rpm once its warm its not as bad still has a low idle.
Also i have a constant engine rattle thinking left front cam tension-er
Also throwing and check engine light odb scan tool shows o2 sensor position two is bad
I was thinking intake gaskets and new tension-er is a good place to start.

Engine cranks but will not start, it kicks back after cranking over for a couple of times i have replaced the crank sensor it has done this once before it kicked back hard enough to knock a tooth off of the flywheel after replacing flywheel and starter it started fine for three months then it kicked back hard enough to break a starter mounting bolt. i replaced bolt had starter checked and replaced again?

MY 2005 chevy silverado 2500 developed brake problems. The power steering pump, master cylinder, and Hydro static something or other has bee replaced.Now the pedal fades with constant pressure. The shop tells me this is ok but today at at a downward sloping boat ramp with the pedal at the floor, it was very scary.Before the parts were replaced this problem did not exist.

I have a 2011 Corolla LE with the automatic transmission. When traveling at a constant highway speed (i.e. 60 mph), the tachometer will start jumping around. It will jump up than down by anywhere from 200 rpm to 1000 rpm. It only lasts a few seconds then returns to normal. The dealer is saying that is just the electronic controlled transmission selecting the correct gear. I have never heard of this in any other car.

I've been watching my mother's 1976 Fiat convertible this summer. It had been taken to the shop about 6 weeks ago and it's been running fine without any problems. I had to leave for about three weeks and now the car will not start.
When I turn the key in the ignition with the clutch engaged, the engine turns, but pressing down on the gas pedal has no effect. The engine doesn't rev nor does it catch. There is gas in the tank and clean oil. I checked all the connections I didn't find anything loose.

I have a 1998 Ford Escort which I drove about 450 miles in frigid weather over about 8 hours in mid January. After arriving at my neighborhood and getting off the expressway, I couldn't get the idle on the car (manual transmission) to go below 2500rpm's. Further, upon taking off, the car was trying to stall, and I was forced to feather the clutch through town driving and keep the throttle up so it wouldn't stall, even with the clutch in. The weather at the time was about -7 degrees (f). The next day the weather continued, and thee car would start, jump to the same idle for 10 seconds, then drop suddenly to 500rpm, then stall out. I wrote the car off, cleaned it out over the next week, and then I tried to run the radio while doing so last weekend. I got the car to start, and run normally. I think it may be a computer issue, but it may also be the temperatures. The car has 207,000 miles on it.

What is the difference between the 2 wire & 3 wire cam sensors. I am installing a 98 4.0 in my nephews Explorer-engine build date of 12/98. The replacement engine build date of 5/98. There have been quite a few differences during this process and thought I had them worked out but the old engine had a 3 wire cam sensor and the replacement has a 2 wire. I have already changed the harness over due to other differences but my main question is will I have to swap the synchronizer or will the sensors interchange? The synchronizes look different as does the cam sensor.

Engine idles erratically after it warms up. Strong sucking air sound from throttle body as engine idles from low to high. I have no codes on ODB II.

I have a 1996 Explorer XL 2 dr. It has the 4.0L OHV V6 and the 4R55E Transmission. I bought it used with 152,000 miles on the odometer. About a month after I bought it I noticed it sounded different. I looked down at the tach and the RPMs are up around 2500 with the overdrive engaged. I turned the overdrive off and nothing changed. I turned it back on and nothing changed.
That weekend I pulled the tranny pan and filter and replaced the filter and fluid. There was the normal amount of debris in the bottom of the pan but nothing major. Now when I drive it it tries to shift into overdrive but when it does the engine bogs down and the O/D off light starts flashing. I know how to do the overhaul but I wanted to get a few opinions before I start tearing into it. What could be wrong .

96 Ford Explorer, 78,000 miles After about an hour on the highway (60 mph), the vehicle slows and cannot increase in speed. It does this until it slows to less that 20 mph. Pushing on the accelerator increases the rpm, but does not result in an increase in speed. It only does this after an hour or more on the highway (city driving does not cause the problem). No one can diagnose the problem; already took the vehicle to the dealership and a transmission specialist (both said nothing was wrong). Hoping very much to keep this vehicle.

My car is taking a long time shifting from reverse to drive in the morning. Do you know what may be causing it and how to fix it. It's a 1995 automatic ford explorer.

I just got a new clutch and clutch slave cylinder in my 1998 Ford Explorer. Driving it home from the mechanic, I'm hearing a sputtering sound coming from what seems to be the lower part of the engine compartment. It sounds like a VW Bug exhaust. I've never heard this sound before. It's troubling that it has appeared now immediately following a repair. I presume there is a outside possibility that it's not the mechanics doing, but that seems improbable. (The engine was revving high right before the clutch blew out last week, so maybe those brief high revs caused some damage? I can't imagine that being the case.) Or was there something in the clutch repair process that could have resulted in this?
I made a recording of the sound here.......

So my 98 f150 xlt 4.6 is having a issue where the truck is jumping from 1500 rpm to about 2500 - 2600 rpm. You know sitting there trying to get up to speed. then all the sudden i look down and its at 1500 rpm. but still not really going anywhere. So i give it a little more throttle or gas and it jumps from 1500 to about 2500. Its been like this for a month but i thought it was crap fuel. What is the cause or maybe a solution?

My 2003 Ford Explorer, Eddie Bauer 4WD is making noises when the vehicle is at 2000RPMs. Below or above 2k RPM's no noise. Sounds like a very angry rattle snake. I seem to drive at speeds that require it to be at 2k RPM all the time. So needless to say as fall is approaching and I have the windows open, my hair is now falling out and not blowing in the fall air. I want to get it looked at, but don't know what to tell the mechanic to look for.

I have a 1998 f150 xlt, supercab, 4x4, 4.6 Romeo (truck production date is 12/97). And I have a oil leak.
Its on the drivers side of the engine. There is a nipple on the head, next to the firewall, directly above where the exhaust pipe and exhaust manifold meet. It looks to have some sort of bolt/flush stud inside the nipple. I have oil seeping by the bolt/stud and leaking onto my exhaust pipe. its a constant but slow drip.
What this is or how to fix it? Is this a common problem? I can take a pic but cant find my camera at the moment.
