Update on the Trailblazer 4200 Vortec

[DeltonRushing]

UPDATE: I just finished cleaning the throttle body and it is running a little better. As soon as I put new oil in it and clean the CPAS it will purr like a kitten! (I hope) I am also going to replace the serpentine belt and spark plugs. I will let you know on the progress, I could have done it without the help of Voymom!!! Thanks!
I have posted picture of the throttle body before and after the cleaning.
I have also posted a video of what it sounds like with the bad CPAS and bad oil.

Here are BEFORE/AFTER pictures of the Throttle Body.

That's exactly how my Envoy sounded when we put the Engine Restore in ours...well when hubby put it in the truck. I had no part in it as I'd rather use seafoam and smoke out the neighbors

If only my envoy sounded like that. Without the issues...
