Trucks acting weard latley...

I start it up, and for the first little bit the throttle is so incredibly touchy....if you just rest your foot on the pedal, applying no pressure, the RPM will jump...Sometimes you dont even have to rest your foot on the pedal, the RPMS will just jump all on there own, After 2-3 mins and it warms up this goes away..

Both O2's are new, Cat is new, Plenum is Fixed, IAC is new, Plugs are new.

 

Maybe you need to replace the TPS.

 

Thats what I was leaning towards, but if it was the TPS wouldnt this happen all the time, not just when cold?

 

Who knows with electronic parts. Get the Haynes out and test it when hot/cold.

 

i once had a tps that surged like hell when cold and acted normal once it warmed up. i'd replace it. keep the old one just in case its not the problem. its nice to have a spare.
