PCV valve?

[JeffBoyette]

Ive noticed my idle is getting a little more "aggressive" or rough. Either way with the cutouts its easy to notice small differences in the idle.

It doesnt sound like a misfire, ive had a recent tune up, running good fuel. But im at 85k miles.

I was thinking pcv valve, but i cant find the fucker... Is it under the intake?
Could this be the issue? I know its past time to get some new O2 sensors.

Your truck does not use a pcv,but rather an orifice.On your truck,it is located on the driver side rocker cover in the rear.i doubt that it is contributing to your concern.Maybe check your I.A.T. mod,Or remove it and see if the idle straightens out.

we have been known to have tps issues causing driveability issues

Ive swapped out the resistor, thinking it was stemming from the warmer weather down here. No change. I dont think the tps because its only noticable at idle with the AC off.

I just found this post from Prof from another thread

Have you checked your pcv valve to see if it is clogged? Do you still have the pcv? Under the intake...not fun to get to...

It could be a minor vacuum leak, or a dirty throttle body too right?
