Engine Mechanical problem
1993 Chevy Lumina 6 cyl Two Wheel Drive Automatic 157+ miles
My 93 lumina euro 3.1 liter will start and run good until it gets warm. The cooling fan don't seem to want to turn on and then the engine acts like it is starving for gas and dies. If I try to restart it right away it wont. I need to let it sit for 30 minutes or so and then it starts and runs fine until it gets warm again. I have changed the fuel filter, thermostat (needed it anyway) and the air filter. Self diagnostic test came up with codes 33 & 35 and the cooling fan also came on as soon as I inserted the paper clip for the test. Is that normal? Any ideas? Temp sensor maybe?
