Help please, totally stumped. My 95 xj 4.0 sport manual had a bad missfire on acceleration so i decided to change the tps. No change. I tested the wires on tps plug coming from ecu and the middle feed wire had a constant flow of 4.83 volts. So i decided to test the feed wire coming out to tps from ecu and it has 4.83 volts. Im confused, isnt the feed wire supposed to receive and not send voltage ???
