Jaime Posted December 2, 2014 Posted December 2, 2014 Back when I was having trouble with my truck shutting off, I adjusted the TPS and the RPMs went up to about 1000 while idling. When the engine is cold it the RPMs are about 750 but when the engine comes up to running temp they climb up to 1000 to 1100. I have done Cruiser's tips 1-5 and 27. I just put a new TPS and cleaned the IAC Any other suggestions.
Jaime Posted December 5, 2014 Author Posted December 5, 2014 Last night I installed a new IAC with the same results. Anybody have any suggestions.
88whitemanche Posted December 5, 2014 Posted December 5, 2014 Tightened up the manifold bolts? Also grab some brake cleaner and with the engine running spray where their are vacuum lines to see if the idle changes once it does it means you have a hole in the line and replace it.... Most of time it ends up being the vacuum lines by the throttle body....
cruiser54 Posted December 6, 2014 Posted December 6, 2014 You are testing the tPS on the Engine side?
Jaime Posted December 6, 2014 Author Posted December 6, 2014 I will be tighthing the bolts tomorrow on my day off. I did spray some parts cleaner last night with no change with the RPM's. Cruiser I'm not sure what you are asking but I am testing the sensor closes to the air box. The one you can actually adjust.

I'm asking if you're following my instructions and adjusting the engine side of the TPS, not the Trans side.
Jaime Posted December 6, 2014 Author Posted December 6, 2014 I don't think I mentioned it but I have manual transmission. I back probed the three wire connector, got my base number, then adjusted it to 17 percent. I did not use the four wire connector.

Jaime Posted December 7, 2014 Author Posted December 7, 2014 It seems like it may have been the manifold bolts. All of the top bolts were loose but not the bottom. Looks like I have another thing to add to the preventive maintenance list. Thanks for the great advice.
