"SERVICE" LIGHT

My opinion is that it is not likely your choice of oil. Something else is not quite right with whatever you did.

The oil was not the casue. Mosty likely one of the other item you changes was the casue. I'd guess spark plugs. What type of car? Did you use the OE plugs, or decide to switch brands or types? If the service light was not on, why did you think you needed to do anything to pass inspection?

Hi,

I have a 1994 Saturn SL2 with 122,000 miles. The service engine light came on my car today. The car feels like it's going to stall whenever I stop at a light. I put the car in neutral and give it some gas so it doesn't stall. Any ideas?

Thanks, Joe

Go to an Autozone and have them scan it.

EGR valve.

We have a winner. It was a clogged EGR valve.

Thanks, Joe

Hmmm, I thought an EGR valve was closed at idle. A clogged EGR should then not be noticeable until acceleration. In fact the way I test my EGR is to take it off and cover the two holes with duct tape and temporarily reinstall it. then idle it see if there's any change. Van

The EGR may not be able to close if it is clogged, i.e., stuck open because carbon deposits are holding it open. That's what happened on my '96 SL2.
