I have a 98 Saturn sl2 4cy. It just started idling fast about 1100 rpm. Now when I start it, it idles fast all the time. Any ideas?

Thanks, Robin

Check the temperature sensors. could just think that the engine is very cold when in fact it is not. You should also be getting a rich fuel mixture which you should be able to smell before the cat warms up. Have diagnostics run. should show up a malfunctioning sensor pretty fast.

Do you know where they are?

Sorry, no idea about specifics on that model. I have an L series which is completely different. See if you can get a Haynes manual for your car. They're usually very good. I understand that 'pep boys' has a free diagnostic service. Never been there but sounds good.

Just a note of warning about PepBoys. I got back my '98 dohc sl2 (>97k) from PepBoys, yesterday. It needed a tuneup (spark plugs/spark wires/ignition wires/filters/etc), oil change, and the blinking battery light checked out. I asked for a free diagnostic, since I was getting all the above done. No can do at PepBoys (at least here in the SFBay area); it costs 100$ to do a diagnostic.

Before the tuneup, the car ran ok, rough sounding, but ok all the same. On the way home, it stalled when I stopped at lights, idled high, really revved up, and finally died in the driveway.

I had to call them to find out that they had noticed only 3 cylinders firing, but hadn't bothered to tell me. And _now_ they want to take a look at it and run a diagnostic.

Caveat emptor with PepBoys.
