95 Saturn SL2 high idle/stalling problems

Saturntech9,

I have had a similar issue with my 95 Saturn SL1. When I come to a stop the car will IDLE at the normal 750 to 900. After sitting for about 1 to 2 mins then will start fluctuating and eventually if the light is long enough will shut off. I have replaced the temp sensor and that stopped it for all of a day. Then I proceeded to check the codes and I got a 13 and 45. I replaced the oxygen sensor and the problem still exists. What ever assistance you can give would be greatly appreciated.

HI SATURNTECH9,
I replace the coolant temp sensor and now the idle is much better. On the other hand I do get a surge flux change up and down while the driving car i.E stall or very low rpm. Also this time I got a code of P0108 then later P0107. Any suggestion?

93 Saturn SL2 high idle/stalling problems

I hope saturntech9 will be among one of the technicians able to read this and provide us with some advice on how to fix the high idling in our vehicle. I enjoined very much the advice that was provided when it comes to the high idle problems the owner of the 1995 Saturn SL2 received back on May 7, 2012. Similar to that situation our 1993 Saturn SL2 had a continuous high idle regardless of engine temperature back in 2006. So, ever since we replaced the lower coolant temp sensor the high idle problem was solved when the engine is running after five seconds on cold starts. In other words, when the engine is restarted and the engine is not cold then there is no high idle problem. Otherwise, the high idle at about 2,000 r.P.M. Will be present for the first 5 seconds only when starting the engine on a cold start then it will drop to a normal 750 r.P.M. Also, we have recently noticed that the warmed-up engine will stall sporadically at traffic lights. There are no visible p.C.M. Codes. We would appreciate any advice you can give us. Thank you for your prompt response.
