I have a 6 cylinder 2000 olds Alero. When I start it from a cold
start it idles rough for about 60 seconds and then runs fine. As
as the engine is warm I have no problems. If I try to drive off
it is idleing rough the check engine light will come on and and go
after it starts to idle correctly. I thought it might be the EGR
valve stuck open or something like that. Any Ideas?
Thanks in advance for any help.
