Newbie
'89 c1500 5.7 tbi with 700r4
Timing is set to 0
New sensors all around (truck sat for a long time)
Tps sensor is showing .49 volts with key on and not running, once it's started it jumps to 1.3-1.5 volts. Idles high around 1500-1700
When I pulled off the old sensor one of the bolt heads snapped off leaving a "stud" and installed the new one with the remaining bolt, the other side slid over the broken bolt. No movement in the sensor itself that I can detect (trying to wiggle it vigerously) and no change in voltage fully closed with engine off. I have a bolt set ordered and am waiting, just need to know if I got a bad sensor or if the broken bolt is the issue.
If tps unplugged during idle it goes back to a perfect idle, replugged it raises again
