Have you had your radiator pressure checked? when there is not enough pressure to keep your coolant moving steady through the system it will cause the same issues.

My 95 Saturn SL2 1.9 will idle very lough when in drive or reverse. Runs fine at about 65mph but still has a little skip here and there. When the Air Conditioning is turned on the car will stall....


TYry doing a static power brake test on the vehicle, with the car in gear, wheels are chocked up so not to allow vehicle to move forward, stand firm on the brake pedal and slowly add gas to the engine, does it dance around and miss fire?
If so you may have a bad coil/plugs/wires under load they may be breaking down they should have been replaced by at least 65,000 miles if not do a featured maintenance on the engine and replace them.

94 Saturn sl1 tbi, started running rough. Changed the plug`s it still no better. It dies if i turn on the air. Lack of power.


Change your ECTS sensor with a brass one, it's the water temp sensor you can buy it at auto zone for 8 dollars and replace it yourself, make sure you get a NEW wire plug harness for it probably about 10 or 15 bucks, it gets corroded then the computer reads the wrong engine temp then it makes the idle rough and run rich.

2002 Saturn SL1 check engine light code P0303


replace the coil it is most likely bad. observe the engine at night or in a dark environment and proceed to use a spray bottle to lightly coat the coil pack for that cylinder number 3 and if you see an arc at the coil or any where else this will confirm a bad coil but even if you don't see any arcing it still may be a weak coil.

It's either a carbon tracked spark plug & boot or a faulty fuel injector.They have alot of issues with the ecotec engine with idle concerns due to injectors.If it misses under a load it's more than likely a saprk plug & boot concern

1999 Saturn SL1 trouble starting when warm


It was the coolant temperature sensor. It was telling the car that the coolant was always cold, therefore when starting a warm engine it was being flooded. $$$

93 saturn sl1 will crank but not turn over


Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too
