Hey there ,

i have gotten this code and have related it to idle control valve.i
changed it and i am still getting the same code.

The problem being that my 1999 sl1 idles up at 2000 rpm then eventually
drops to 1200 rpm's and runs rough at a stop or idle .....any
suggestions??? Have changed wiring ,spark plugs and idle control valve .

Look for a vacuum leak somewhere. If the intake manifold is leaking air, the
computer will add enough fuel to make the air to fuel ratio 14.7 to 1, even
if that means that the engine runs faster.

Then, the computer notices that it isn't idling as low as it should, and
throws codes.

Good luck!

This is the same as what happened to our 99 SL1. We took it to the
dealer and they found and Intake Manifold Leak and said it was not
covered under the Ross-Magnusson Act (EPA) and the owners manual
stated only the Exhaust Manifold was a covered repair. After much
fighting back and forth and no help from the zone office (Customer
Care Telephone Number) I told the Service Manager I would pay the
$600+ repair bill and then take them to court. (Court is a block away
from my job) they relented and charged me only for the gasket that was
needed.

For good customer relations is what they sited.

In 2004 New York is like California in its emission controls warranty
8 years 80,000 miles which was signed into law by the Governor so
folks that have this problem in at least NY can get some sort of
relief.

I had just turned 36,200 miles mark when this happened. And the car
makes different noises now then when we brought it in the shop for
repair. Go figure. Saturn of Albany is one of the worst places to go
for any repair work in my opinion.

Thank you .i was hoping no one would say that .lol ....i am keeping it as a
last resort ......but it probably is the problem i am thinking
...............go figure that this has only happened since it was in at a
saturn dealer for an oil change and a new door lock . then they tell me
that the upper motor mount is cracked and so i let them change it and then
they tell me that the head gasket is blown as well ...hmmmmmmmmmmmmm??
