92 nonturbo well heres the deal it starts up fine idles fine but when its been runing for about 20 mins it doesnt want to pass 4000rpm i changed the o2 mass air flow pcv and the tps all vacum lines are hookeed up right and do not leak i also have shitty gas milage about 180 miles to a tank and top speed is 85

could that also be the reason why the coolant light stays on even though i know the levels are fine i mean the operating temp is running temp and everything.

i would also check ur ecu, that happened to my friends gst and once his car would warm up it would run like ass, check to see if it smells like rotten sea food under there, then go from there

conclusions are blown headgasket hundreds of dollars later i think i should have looked at it a lil differently i guess resedue in the exhaust milky oil the coolant leakin into the cylinders caused it to skip under high rpm and cause of loss of power thanx for the help though i just wish i known it sooner before i put the hundred and hundreds of dollars that didnt fix nething :thumbdown

good news gasket only 33 bux and a couple hours of my own time

with the coolent sensor. my car when it is cold runs good but when it warms up run like crap and when i turn it off.and try to start it again all it does is crank and dump fuel.
