It could be a few things depending on how old the car is and other things. The easiest thing would be to have the fuel filter changed as it could be getting clogged and the increased flow of acceleration actually plugs it more. Others will probably add other things to check too, but this is inexpensive. I believe the fuel pump could also be going bad if it is an older car. It's probably fuel starved, possibly low fuel pressure or a restriction in the fuel line.
My 89 jeep Cherokee surges at idle and sometimes stalls but runs fine once you are going what could cause this?
The idle sensor needs changed. Just had mines changed, I was having the same problem as you are having
you need the fast idle adjusted on the engine you may have idle set where it sounds fine in idle but not high enuff when dropped in gear.
check the pcv valve and hoses if there is a vacuum leak here it wont idle
Hey there, seems to me like you coil/s are on the way out. test with an ohm meter and look up specs for your vehicle from dealer.
check your acceleration wire.
Try to clean your throttle body. If you disconnect your battery or get a bad connection your throttle body will act up if it is dirty and it will not idle.
fuel injector, throttle body.
Possibly a bad alternator or battery.
If a 1991 Honda Accord dies when the vehicle stops or slows down the Idle Air Control Valve may be broken. Once replaced the car will be able to regulate the air to fuel ratio appropriately and avoid stalling.
Check the cam shaft position sensor
have you checked the spark plugs and wires? if not try replacing those... my 95 eagle talon did about what yours is and I just replaced the plugs and wires and it runs like a top (with over 200,000mi on it!)
I found out what the problem was - the idle air controller
A clogged fuel filter can cause a Mitsubishi Galant to idle rough for the first 10 minutes it is running and then it runs fine after that. A fouled spark plug can also cause this issue.
Check the fuel pump and fuel filter.
OK, heres the deal, i got a magna tr. Starts fine when cold, and runs fine aswell. Revs up easy with no roughness. Drive around till temp reaches normal, and car dies whenever not in gear something to do with idle i reckon. plz help me out... its driving me crazy
sounds like a vacuum leak
on my 87 Chevy caprice just happen today, my car would idle for a while then die. Turns up my carb was bad. Changed the carb, ran like new again.
Coolant temp sensor
The computer has either forgot how to controll the idle, usually caused by a weak battery, or the idle control motor has failed.
Possibly a stuck or sticking EGR valve.
If it runs fine other than the idle could be your idle air control valve or IAC valve.Had this problem with a 98 explorer. M.Cole An engine needs 3 things to run............air flow, fuel flow, and properly timed ignition spark. When did you last replace the spark plugs, the air filter, or have the engine tuned up? A further thing to look at is the fuel pump, for fuel flow pressure, and the fuel filter, which may be clogged with dirt. ---- If it stalls at idle but runs fine if you give it gas you have a vacuum leak or a bad idle control motor.
Remove, clean or replace the IAC (Idle Air Control) valve.
Have fuel pressure checked. May be fuel pump. Change the fuel filter first to see if it helps.
