hey guys, last night coming home from a truck GTG i noticed when i got home that my truck randomly was idling about 200 RPM higher than it ever has before, It usually idles around 750 but last night it was idling around 950 or 975. I did nothing out of the ordinary with it except on the way home a buddy and were playing around on the road where had come up beside me and then id accelerate up maybe 10 MPH then back down, we did that maybe 4 times but thats it. I cant imagine that that would cause my idle to ramp up like it has.

Is there anything i could/would/should check as to why itd be ramped up to almost 1000 RPM from a normal 750 RPM. My initial thought was APPS but i have no surging or dead pedal or anything to associate it with.

So any suggestions would be good, id like my truck to idle back where it always has @ 750 RPM

 

Check for codes... There could be a APPS problem start to happen but not manifested into a full dead pedal problem yet. I know I don't suggest adjusting the APPS voltage but you could try a APPS reset for the ECM.

Now if you find that the voltage for the APPS is off its setting for the ECM (not the PCM which is cruise control) then I would say its time to replace the APPS sensor because adjustment isn't not going to fix the wore out carbon track inside...

 

well today i drove it and its fine now....so i have NO CLUE as to what it could be now. Codes were all normal ones ive seen n the pest except a P1475 which is a 5 volt signal high code

 

Remember the APPS sensor is feed from a +5V line... so that might have a lot to do with your problem...

 

maybe but that has been there way before this happened....i think its a code in conjunction with possibly my smoke switch
