Yea as title says got an idle problem on my firebird its a 91. Sometimes when its idling in drive or it revs and actually sticks and if u take your foot off the gas its starts to drive by itself?????????????? any idea wat this could be and also when this happens the service light comes on.

 

check for a vacuum leak, you might have a hole in a hose where it's sucking in air.. I had a hole in a pcv hose and i just taped it off and fixed the problem

 

Just checking to see problem was fixed. ^ I agree.
