My car is a '91 lx convertible, I recieved this car from an auction!
It had an engine fire I suspect from a power wire I had found ran directly to the a/c compressor? Anyways I replaced engine harness and main harness Computer/ Used. Well It runs fine BUT my check engine light is on so I took it to autozone to have the code checked. The codes were to low voltage to the throttle position sensor and to high voltage to the tps. I am on a tight budget so I went home and loosend the tps and moved it a bit. check engine light went out at idle but at any throttle comes on? Don't know if maybe the tps is bad or something else is making that code read? Only mod is underdrive pulleys!I am having a migrane need some serious advice!!!!!!!

welcome to the board.

check the wires to the TPS. you should have key on 5 volts, ground and return. the wires could be bad or the TPS could have an internal short.

good luck.
