my 03 , automatic starts and idles fine cold but after it warms up it will start and die unless you give it gas? runs fine all the time otherwise, any suggestions????

 

Do anything to it recently?

You can always try the throttle re-learn procedures...

I haven't , but it has sat for about a year without driving much. I will try that,
thanks !

 

Yup, mine has been like that for years, happened after a test pipe install. Still happens with stock cats , HFC etc etc. gave up on it.

 

tried resetting the throttle, no luck. Any other suggestions???

 

Sounds like a vaccum leak?? check out ur vaccum hose.

 

Possibly there is a light on the dash that has been on for awhile indicating the engine needs servicing?

 

Car had no codes or lights. The good news is here was the fix:
removed the throttle body and throughly cleaned the throttle body.
***make sure not to push on the flap in the throttle body, it will break the mechanical/electrical mechanism and you will be replacing your throttle body assembly***
I didnt do this but a friend of mine did.
thanks
