Problem during a cold start-up

wolfmania · April 13th, 2010, 12:59 AM

Hey guyz,
I have a problem with my 2000 Mustang GT, when i try to start the engine in the morning (its cold), it starts for half a second the rpm raises and then the engine shuts down, unless if i manualy push the accelerator untill the engine gets warm. Some told me there must be a problem with the (Automatic Choke). Is that right? if so, can I fix it at home? and how?

Thank you in advance.

You don't have a choke its fuel injected. You do have an IAC (idle air control). That that is usually the cause of most idle problems. Although it could be basic like a fuel filter (not enough pressure when you crank it). Have you done tune up lately?

How cold is it?

hmm, no i didnt tune anything, and the weather is not THAT cold, its around 28c, but i meant when the car is parked for more than 5-6 hours, i get this problem..

does it gold idle when warm?

Also when cold and you on the gas to keep rpms up does it hang there or bounce around?

when the engine is warm i have no issues, it starts properly.
and when its cold, i accelerate it a little and the rpm stays stable (not bouncing), unless if i remove my foot from the gas, the rpm starts to go up and down, and then shuts down..!

i did some searching and saw that a guy clean his air idle control valve...so try that then report back

there you go!

Tune i mean tune up. Spark plugs, fuel filter, check air filter. And clean IAC after, although that can help sometimes it doesnt cure it. Start with tune up if you haven't done it before...
