IAC or TPS
Case: 91' F150 5.8L 4x4 auto
Symptoms: High idle in park. I warm it up in the morning and it starts up cold at about 1300-1500 rpm and it takes kinda a long time and it will idle down to about 800 once warm. Then I drive to work and when I come to a stop in Drive the idle stays down, but when I get to work and put it in park it idles up to the 1300-1500 range and doesn't idle down.
Diagnosis: I pulled the wire off of my TPS and the idle went back down to about 800, when I put it back on it revved back up. I don't know that this neccesairly means anything or not, please help. Also, unrelated, when cruising down the highway changing lanes I hit the blinker and the motor revs up 200-300 rpm. I just put a turn signal cam in it and think that, that might have something to do with the problem. Any help is appreciated
