Ok so my truck has 275000 on it and the motor went bad. So i replaced it, with a remaned one. Replaced all the coils and injectors and plugs when i installed it.
But still has a funny idle /lope to it and gas milage sucks the lope can also be felt at driving speeds. Plugs look great. I tested the O2 sensors and the VCT solenoids they seem good. And also the truck will not throw any codes. I checked compression and all cylinders are 175- 185 psi, so I know the motor is good and timing is on.
I've done a vacuum test and that reads 20 and steady, so no leaks.

I did find a rock had wore thru the white wire on the connector below drivers door along frame rail, that leads to the FPDM. So i repaired that, still runs like crap.

Im getting frustrated because the old motor with a bad cam lobe and a bad rocker roller ran better than this one.

Am I missing something????

Im starting to think the PCM could be bad.
