my car has been idleing very rough lately, it has been dropping to like under 500rpms and then raising back up to normal. but two days ago it shut off instead of going back up to normal. so i turned it back on and it just shut off again. i tried agian but then instead of letting it die i revved it a little and started going and once i was going it ran fine but when i came to a stop it died again. so i had to drive it home without stopping. for the next two days it did the same it just starts then shuts off. but when i woke up today i tried it and it ran fine drove it around a bit and it idled perfect. but then i noticed when i start driving for longer periods of time the idle starts to get rougher as i drive but did not shut off.
could it be my cooling system??? the day it shut off was extremely hot.
if someone could please help me i would really appreciate it.
car shuts off please help!!!!!!!!!
hmmm... sorta the same thing is happening on an engine my friend and I just installed in his 93 Camery.. Maybe it's one of these things:
1. Air in the fuel system. Sometimes air can get into the fuel system and cause a bunch of problems - Ive seen this happen for lots of reasons, sometimes as simple as running out of gas. I'm not sure if the KA has it or not, but sometimes engines have a little nipple on/near the fuel rail that allows you to purge air from the fuel system as you have the pump on or cranking... Although then again a lot of newer cars have automatic systems that do this-- I dont know which the KA has cause I havnt had the need to check...
2. When is the last time the car had a good tune up? Think about changing your plugs/wires/cap/rotor/fuel filter/etc... you probably need it anyways. This simple tuneup sometimes solves some of the most confusing problems.
3. Your EGR valve might be stuck, or gunked up with crap. Check that bugger out.
4. Check all your vaccum hoses and routings... make sure you have no cracked or disconnected lines.
5. Is the check engine light on? Find out if the ECU is throwing any codes (like maybe O2 sensor that is making the ECU pull some timing?)
6. Is your air filter clogged?
7. Bad gas-- make sure youve got some good gas in there... bad gas can make your car run really crappy too.
Thats all I can think of off the top of my head... that should get you started anyways. Good luck man!
