Suburban hesitation
#42
But my year doesn't have a pcv valve. Its just an open port on the drivers side valve cover at the rear and the hose goes to the top middle of the intake manifold. there is a baffle inside the valve cover that is supposed to prevent oil from being sucked up. There is no replaceable part.

Anyone interested in the found confirmed issue, it was a bad connection of the ground wire for the coil packs that goes to the front of the engine block by the oil pan and the crank pulley. Sub finally would not start, had it towed and after 2 days of diagnostics they found the bad wire termination and repaired. No issues since.

Thanks I will check into it. I do all my own work, I used to wrench myself but now I'm an electrician. The way its acting now is like its missing on one or 2 cylinders. almost like the coils are going bad. It only does it after it warms up and has been running for a few miles. once its been doing it for a while it still has good fuel pressure and thats why I am leaning away from the pump. I can do the work no problem, its the spending $350 or more just to find out that its not the pump that I have issues with.

several forums and having to re-join this one because my name/p-word didn't work, I finally found your post and solution again.
So, I need to know if this continues to be your solution. I hope you are still on the forum!
Thanks ahead of time!
