Hi HwnBoi, Again, I would check/replace the throttle position sensor and have your computer scanned for trouble codes. Check for black smoke from the exhaust that would indicate a lean fuel mixture. Good luck!

I have a 2007 Saturn Aura that just started doing that too. I would like to know why also.

sounds like a vacuum leak caused by heat making a split hose expand when at temperature. Try warming it up and then inspecting for split hoses/using the gas method locate leaks.

I have a Saturn 1992 SL Sedan with 164,000 miles. I am having a major problem with the car cutting off while I am driving at a fairly constant speed or when I am idling at a stop light. The engine will shut off, along with the power steering and all other electronics. This happens when at a stop light only after I press on the gas to accelerate from a dead stop, but I am able to put the car in neutral and start the car again (sometimes it takes a while to restart). We tried getting the electronic control module repaired, but this did not fix the problem. We checked the oil and it appears to be of the correct viscosity for the engine. We are at our ends as to what needs to be done to fix this dire problem. Thank you for your time! 8 Answers

1992 Saturn SC2, 123k miles. The car was bought a few months ago, and has run fine for short trips, and an occasional joy ride. About 2 weeks ago, I though I got some slug gas, and have been putting HEET, that seemed to work. The car runs great, then has trouble staying lit, and seems to lose revs to either dying, or coming damn close. Only occurs after has already had "a good run", and been turned off for a bit. Only happens whith initial push on gas pedal, and when down shifting..automatic 1 Answer
