I bought an 89 xj renix 4.0 a few months back after someone hit my 87 and its had a bunch of issues since. I bought it not running, fuel tank was full of rust, injectors were shot, stuck valve w bent pushrod among other things. Ive got it pretty well driveable now but whenthe engine is up to temp and i slow down to get off the highway and stop or just stopping from cruising in 4th gear lockup, the engine wants to die. I have replaced the O2 sensor w a oe bosch unit, cleaned the iac from my wrecked renix that never had this issue. I have tried 4 different throttle position sensors now. The one that was on the 89 when i bought it, the one off the 87 which looks original, and 2 new ones from autozone now. None of them seem to want to adjust into range following cruiser54’s write up. I have refreshed the grounds and replaced both battery cables. The multimeter reads 0 ohms resistance from pin B to ground on the engine side harness. The reference voltage is 4.44 volts(which seems low to me maybe?) and all 4 sensors will only adjust the output voltage up to about 0.2 volts. When i do this the engine revs to about 2.5-3k rpm and doesnt come down until i turn it off and adjust the sensor back more towards the middle. What am i missing here?
