pearlywhite90ls Posted August 24, 2005 Share Posted August 24, 2005 I am the owner of a 90 ls 400 and have been experiencing some idle problems. to start, when i dont start my car for any longer than about 3-6 hours, before it warms up, the idle is extremely rough and rpms very low almost to the point that the car stalls. i have a feeling this could be old valve cover gaskets. if any one has ever experienced this problem and/or has replaced these gaskets please give me any tips on the project. i consider my self to be a little below experienced and could use any advice available. also when i come to a quick stop my car will sometimes stall could this be related if so let me know... thankyou Link to comment Share on other sites More sharing options...
