Default "SERVICE" LIGHT

Hi,

yesterday 'cause I have to go through inspection I changed plugs, pcv,
and oxygen sensor, and added a quart of oil... 10w-40 (usually calls for
10w-30)... drove it out to mom's... fine... on the way home the
"service" light comes on... all the connections seem good and it seems
to run fine... is this just the result of the 10w-40 bumping up the oil
pressure a bit and I should just change back to 10w-30 immediately? or
more serious?

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.

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

Thanks,

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.

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.
