Not all codes will trip the check engine light. Eitherway, the TPS should not be reading 5v, what wires are you connecting to to test and are you using a digital volt meter? Let us know.

Yeah, you're right. Could be an O2 sensor or something in the computer thinking the mixutre is rich when it is really lean.

Most times I've seen it, it has been a bad vacuum leak but these computers can really add problems if they try to correct for a non-problem.

Good suggestion, especially since he mixed up some custom fuel. :-)
