I have water in the oil on 91 3300 century. Car has 100000 miles. Is it worth taking apart and replacing heads or gaskets?
Won't sart back up until car cools down. Like I said it starts an runs fine when it has cooled down but after driving or running till its warmed up it'll die out. I've tried changing spark plug wires, MAF, crank position sensor, ignition control module, and tried using a injector cleaner in the gas but nothing has worked. Help me out please.
Ive replaced fuel filter, fuel pump, fuel injectors, injector o-rings, fuel lines, throttle body kit, throttle position sensor, abc throttle body chip, mass air flow sensor, coil packs, spark plugs, spark wires, water pump, cadallidic converter, crankshaft sensor an quad driver module ( ECM component board )
it just started happening, but only seems to occur when the throttle is pressed, either from driving or from pressing the linkage from the engine
the car starts but will only run about 10 seconds then dies.replaced fuel pump and filter.i have 32-34 lbs pressure running and 42-44 not.replaced ignition mod still same thing..towed it to gm dealer for diagnostic and their suggestion was crank sensor so i replaced that also with no change.spray ether direct into throttle boby and motor will keep codes on stumped on this
