I have a 1997 saturn sl2 dohc. It has 189,000 miles. I started having problems with it about 3 weeks ago. The temp gauge started to fluxuate between cold and the 1/4 mark and my SES light came on. It usually happened while at a dead stop. I took it to a local auto zone to plug in a diagnostic machine to it. It said that it was a problem with the transmission fluid temp sensor. I replaced both that and the engine coolant sensor, just in case. It did ok for a while, but then it started again. When the gauge goes towards "c" the engine will rev higher, and when warmer, it'll idle back to normal. So I replaced the thermostat thinking that would end it. As of tonight (4/13) the gauge went up to the mid-mark then back to cold while I was driving and my SES light came on again! Ugh! Im just about out of options. HELP! Thanks.
have the same problem?
