"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? ttyl Frank |

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? Ed |

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 "C. E. White" > wrote in message ... > > > Frank Matthews wrote: >> >> 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? > > The oil was not the casue.

Go to an Autozone and have them scan it.

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

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. Ken "Van&Joan Hada" > wrote in message ... > Hmmm, I thought an EGR valve was closed at idle.
