...the cheak engine light comes on while crusing or it sits for iono, 5 minis? i cheak the codes, says the TPS sensor is wrong, ok well i replaced that, that code went away, then the MAF went, ok one of the wires was gone so i replaced that, then it was having problems with the fuel pump reley, replaced all 3 of those releys in that cluster on the fender. now its back to TPS is wrong. also has a code of a lean O2 sensor after warm up now...

everything is fine, MAF has all 3 wires, TPS is adjusted right, i don't see any problems with the fuel pump reley, it doesn't stick or anything like it was shorted like the computer says...

i also had my timing a bit advanced which made the code come on not as often. but i corrected it and it comes on everytime i'm crusing in any gear, and temp, and all that...

i know this is kind of vague but maybe somebody had the same problem and would see this...

 

Exactly what error codes are you reading?

FWIW - The MAF on a TPI should have five wires, not three. TPS voltage should be 0.47-0.60V at the closed throttle position.
