[QUOTE="T-Rex Jeepster, post: 437236, member: 19821"] I worked for Toyota during the advent of EFI....And we got a TON of ECU problems in because people were wiring into any power circuit they could find for lights, Amps etc. And the circuits they tapped into that were ECU sensor power/ground circuits and threw off the "Balance" of the circuit. Causing the ECU to react to what it thought was a problem by reading the change of amperage in said circuit. I'd strip all added wiring as a start and see if that helps. [/QUOTE]
