Default Saturn Computer Issues North Carolina


My engine revs wrong. I was told once that it was a computer issue, but the local GM dealer refused to try to reprogram it. First it reved too high, which I got used to. Now it's dying whenever I let up on the gas. I love the car. How does one find help for this sort of thing in North Carolina?

Sounds more like a vacuum leak to start with.
Not sure why it's stalling till we find the vac leak.

Year/model/mileage?

Default Thank you!

I hadn't thought to check that since the GM people got me thinking about the computer.

I have a 2000 SL2 with over 300,000 miles. The high reving has been going on for quite a while, and I've heard that happens with this model.

Check the vacuum lines as derf said, also make sure your air filter, tubing, and throttle body is clean

Vac leaks usually cause high idles.
Vacuum lines, throttle body gaskets, intake manifold gaskets.

Can also be physical -- throttle body plate sticking partially open....

Sometimes it is electrical; throttle position sensor goes bad, Idle air control valve metering too much or too little air

can be mechanical -- egr valve is clogged w carbon deposits and either does not move properly or airflow is restricted.

I'm not throwing all that out there to intimidate you or look smart-- just to make the point that there are a myriad of possible causes to your woes -- it's taking the time to slowly walk through the diagnostic steps to figure out the root cause that makes the difference
