My 95 Ford Probe is idling at around 450 RPMs and I'm not sure what the problem is. I have tried replacing the fuel filter already to see if that would work at all and, it didn't After doing some research online I have seen that it could possibly be an Air-Flow sensor.
View 7 RepliesOk, I have a 95 F150 5.0. It's sat for 6 months with the engine taken apart. I just finished putting everything back together with a new alternator. Well, I pulled a bone-head move and forgot to connect the harness when I fired the truck up. Other than not charging though, it ran fine. When I connected the harness, it began to chirp and shudder at low RPMs and squeal and vibrate at higher RPMs and it over heated VERY QUICKLY.
So hot the case was too hot to touch and the pulley smoked the belt. The engine didn't even have time to get up to operating temperature. I've had the alternator replaced twice, and this last one tested good putting out 14.5 volts. The work I did on the engine was to replace the valve springs, install a direct drive timing gear, replace a spun harmonic balancer, bypass the smog pump because it froze up, new distributor, a new ECU and O2 sensor.
This problem was sporadic. First time cranked it till battery died when I charged it it started. Second time I replaced the battery and it started. Now it did it again so I bought a distributor package I'm putting it in tomorrow and will update the results. Checked for spark and didn't see one.
View 6 RepliesMy son has a '93 Ford Probe that is not getting power to the key switch. He has power to the fuse box but that's it. Seems someone that was working on it for him and hooked up the battery wrong, blowing fuses. Replaced ALL the blown fuses but still no start. My question is are there fuses or fusible links from the fuse box to the ignition that could be causing this problem or is the problem in a different area?
View 6 Repliesdiagnose a problem with their 1995 Ford Windstar. The van slowly dies when idling. It runs for a few seconds after being jumped and then the dash lights slowly dim after which the van stops running. We replaced the battery and the van ran for about a day or so without issue. However, the problem is back. I suspected the alternator was faulty, so we pulled it and took it to a parts store to be bench tested. It was tested twice and passed both times. Does this sound like an alternator problem? Could there be an issue with the battery cables? What else might be causing this?
View 10 RepliesI have a 95 4.0 EFI inside of my 83 Ranger. Once the motor warms up, it starts to have an idle issue. I have to press the gas, in order for it not to cut off. Here is a video I posted a while back. A person suggested that it could be the MAF needed to be cleaned. I did that, and it did not work.
View 9 Replies I have a 2005 Ford Ranger 4.0 V6 2wd Edge, with around 175,000 miles. It runs great, however the RPM's are slow to return and it seems to idle a little high for longer than you would expect when starting the engine. For example, exiting off the freeway with the clutch depressed, the RPM's will drop from approximately 2300, pause at 1800 for a second, then drop and pause at 1100 for a few seconds before returning to idle. If stationary and rev the engine, they seem to drop back normally.
So far I have changed the IAC valve and checked for vacuum leaks (not sure how exhaustive a check it was but sprayed every joint I could find). My mechanic agrees that it is abnormal, but has suggested that we wait for it to worsen enough to throw a code rather than spend a lot of time and money replacing things that may not be a problem. Also the throttle cable appears to be functioning normally and not sticking.
1995 ford ranger with 4.0. It idles rough. Replaced MAF TPS fuel pump fuel filter fuel pressure regulator upper o2 sensor. IAC.. still idles rough RPMs drop. It isn't as bad since replacing MAF but still not right. What else is there.. Cleaned out the air intake port it was gummed up. Don't know what else to do?
View 3 Repliesbacked out of the garage fine later in the day went to put it away started hard would not idle and only rev to 2500 .cleaned map sensor,egg valve tested and it works.cleaned the IAC and that works ,fuel pressure is 58psi. starts hard it would idle now it doesn't dies, no code . with 58psi could the pump still be bad? it has 18 pounds of vacuum. where is the vacuum line for the fuel pressure regulator on the motor?
View 14 RepliesI got a 2000 f250, 5.4l, I got a check engine light bout 2 weeks ago and didn't experience any driving issues. The code was p0171, just recently I've been experience troubles idling, if I let my truck idle for about 3 minutes it will want to shut off, also on acceleration the hole truck bumps, feels like I'm in an earthquake. Where I should start with this problem?

Will not restart until cools off. Have replaced: coils and ignition module, fuel pump and sending unit, ignition cylinder and ignition switch, oil pressure switch. Engine light does not come on. (bulb is not burnt, comes on when starting). Have checked all grounds.
View 5 Replies1995 pickup truck 2.4 liter 4 cal 4WD. I have a new problem- I drove out to a favorite spot in the mountains (up a dusty road) and when I got to the end of the road my truck was suddenly idling REALLY rough. I was able to drive it home and it runs "OK" as long as you stay on the gas (I say OK but it does want to die and especially wants to die after it warms up and then harder to restart until it cools)- as soon as you let off the gas the idle is on the extreme side of rough. It did not act like a fuel filter has historically (hesitate when giving gas), but I had a filter so I replaced the fuel filter anyway.
I also pulled the air duct work and cleaned it all out, put a new air filter in and used CRC MAF sensor cleaner on the MAF sensor. I did pour in a Chevron fuel system cleaner but it would likely take a tank full at least to work and it does not run good enough to run a tank full through. I put in all new plugs (gapped) and checked resistance on the plug wires and cap- all seems to be acceptable. I checked all the vacuum lines and did replace a couple that were dry and crumbly. I am now at a loss,
I have a 95 Celica ST (so it has the 1.8 7A-FE engine). When the AC is turned on and you rev the engine, when the rpms come back down it almost dies.
So say the engine is idling at 700 rpms with the AC on and I rev it up to 2,000 or something. When the rpms drop back down, instead of stopping at like 700 they go all the way down to like 400 or less and it almost stalls out. After a few seconds it comes back up to 700.
What does that sound like? All the vacuum lines are brand new, the throttle body/intake and egr valve were all completely cleaned of any carbon buildup.
My 95 Concorde, when I am at a stop, will sometimes hiccup/sputter while idling. It will also sometimes do it when I push on the accelerator when speeding up from say 35mph zone up to 55 – it will do it a few times and then smooth out. But, when I a get to a stop light, it’ will hiccup/sputter a few times – a couple of times it seemed real bad and the car seemed to shake.
When it does this I don’t notice any movement in the RPM needle and seems to idle normally; It’s never died and starts just fine.
The muffler needs fixed – has a hole or something. I was thinking of getting an oil change, replace the air and fuel filter, first.
I have a 1995 Nissan Maxima that dies after sitting and idling for around ten minutes. It also has been dying at stoplights, etc. It runs fine if I get the rpms above 1000. When it dies it restarts but often I have to push the pedal to the floor for a few seconds, then it seems to catch and run as long at the rpms are up. I have taken it to a place and due to it's age they couldn't do a diagnostic check on it. I've had the exhaust system replaced (it needed it), the spark plugs replaced, the coolant temperature sensor replaced but still no luck.
View 2 RepliesI have a 2005 Camry SE V6 with 73000k I just got it out of the body shop yesterday and everything seemed fine. i started the car up a short time ago and it stalled out when attempted to drive away. its idling at 400 rpms? I feel that the guys at the shop disconnected something.
View 1 Repliesi got a problem with my 96' 2.4 auto cavalier. It idles really rough at idle. I've replaced alternator, battery, idle air control valve, intake, plugs, and the fuel pump in the last year and a half. I've noticed that the rpms will fluctuate between about 625-675 when it's idling rough. About once every 11 seconds the car will rev up for a moment and will idle smooth but then it idle rough again. Every one in a while it will throw trouble code p0200 random multiple cylinder misfire.
View 14 RepliesI've been dealing with this for some time now because it hasn't seemed to affect my performance when I am getting on it, but when I am at idle the rpms will surge ever so slightly and i can watch the needle on my boost gauge bouncing up and down. i have a WINtake on the car and it started ever since i installed that. I am wondering what this could be. I've already taken the whole intake out and reinstalled thinking i had a leak somewhere. even tried swapping my maf with a known good one off the lot on a brand new R.
I read somewhere that someone had their maf in backwards. could this be the issue? I don't have any power loss that I am aware of. in fact, if its down on power now, i would have a hard time believing that it could be much faster with what i have done to it. this idle surge will get worse when i have my ac on also. someone make me realize that I am missing something stupid and simple here so i can have a normal idle again. I am half tempted to put my stock intake back on to see but i no longer have the turbo inlet plastic pipe to test it with.
Why is it that after 15 minutes of idling the coolant starts to boil up and spill and the car begins to overheat?
View 2 RepliesMy car is idling high while driving and when coming to a stop. I do not have a rpm meter so i don't know what my rpms are reading. What could be the problem?
View 1 RepliesMy 1995 Toyota Corolla DX with 180,000 miles is missing. It was missing intermittently, especially when idling and cold, and especially when I drove short distances to run errands and then restarted it. It got to the point where it was missing even when warm, and would stall out when idling (always restarted eventually). I took it in to a shop, and they replaced the spark plugs, spark plug wires, ignition coil (which was fried) and the distributor cap and rotor.
All of the low speed and idling problems are solved. However, it now misses intermittently when I drive on the highway, only when giving the car gas at speeds of 45 mph or higher. It doesn't miss when I am coasting, regardless of speed, and doesn't miss at all under 45 mph. This car drives too well under 45 to be headed to the scrap yard yet.
