My 89` F150 4x4 5.0/302CI. has a lean running condition.Testing my TPS I found my voltages to be OK! 0.5V to 1.0 at idle and 4.0V to 5.0V wide open.But my resistance ck. is 895ohms at idle and 2250ohms at wide open throttle.The {haynes} book states 3ohms to 4ohms at idle and 350ohms at wide open.I`m trying to verify if the book specs are correct before replacing the TPS.Can I get some help!
