hello welcome to the site
does the idle ever surge ?
Customer: replied 7 years ago.
no it always stays below or at normal idle
Expert:  MASTER TECH replied 7 years ago.
ok if you hold the throttle @ 3000 and then let off right away will it stall ?
Customer: replied 7 years ago.
When it is idling bad you need to keep your foot on the gas pedal. You want me to try it when it is idling normal?
Expert:  MASTER TECH replied 7 years ago.
yes you can try this.
this sounds like you have a bad idle control valve.
has the throttle body been cleaned ?
a throttle plate that has carbon on it and the idle screw these are known for causing this problem.
i would have the throttle body and the idle screw removed and then cleaned and then readjust the idle
if this does not correct this then a new idle control valve will be needed.

OK talked to my son and here is what is happening. When this happens the car will not idle at all. It dies. You need to give it gas to keep it running.
Expert:  MASTER TECH replied 7 years ago.
ok perform the step i posted .
this is the first place i would do before replacing the idle air control valve.
Customer: replied 7 years ago.
I will check that out and let you know what happens.
Expert:  MASTER TECH replied 7 years ago.
ok do you need directions or are you going to have a shop do this ?
Customer: replied 7 years ago.
OK I cleaned it out and it ran fine for a day then today it wont even idle. It takes a few times to get the engine to start and then if you let off the gas it dies.
