The car was running great last night,I was even doing 120MPH on my way home,this morning I start her up,and I was like what the hell,I put premium GAS and a bottle of Chevron still nothing, it still stutter and shake when idling after a cold start.

any advice

 

Check engine light on?

 

IT was on last week after I reset it,it still hasn,t come back on.

 

What was the code?

 

that it was running lean,possible air leak,which you advise me to spray with carb cleaner to see if the idle changed.
i did that there was no change in idling.

 

Maybe Mass Flow is going bad.

 

It's probably a vacuum hose since there are a gagillion of them on the car. Look near the throttle body tree, and around the air box.

Even if they are attached they can be rotted and leaking.

Also clearing the code is not the same as fixing the code problem. If you clear the code, it sometimes takes 120 miles until the car decides it needs to fire the code again.

What is the code number? Then do a search on it and see what the usual problem with this car and code is. Normally that will solve it.
