hey, Ive got a 88 gta\350tpi
Today my check engine light came on. My car has been missing a little bit lately. I turned it off and it didnt want to start back. Finally it did and i made it home. Now i get a code 21 for the tps. Some times i get a cod 21 and code 22 and 34 but not always. Sometimes my car will start ok and sometimes it wont. the gauges for my oil pressure, alt, and temp all jump around on their own and when i push the throttle down. I washed my engine bay some today so im thinkin maybe i got water in something?


any help would be great

thanks

 

Ive also noticed that when I turn the key on the lights dimm and when its started that it seems like everything is low on power...
My headlights wont come up and everything is dimm

 

You may have shorted something out that is causing a drain on the battery. Water+Electronics=Bad. You dont put the toaster in the bath with you do you? Have your alternator checked and check for high current drain while running. Then figure out whats wrong with your sensors if that doesnt solve your problems.
