I have a 94 Chevy k1500 and its running like ****. I runs fine when it first starts for a while but as it warms up it gets s rough idle in controllable throttle no power and as of right now I can't start the truck with out the rpms running away to 3,000

 

PMD get a new one and if it is not relocate it.

 

thank you I'm new to the truck. and it was already moved but only to the top of the manifold I was thinking it was the pmd but I'm not sure

 

ya move it behind the bumper or at least to the fender. you will probably have to get a longer extension wire

 

Might want to do some legwork first like checking codes?

J Could also be injector pump head warped and as it heats up its out of its tolerances

 

Warped rotor does not cause run away that I know of-if anything it causes hard hot starts.
