Personal opinion, to each his own, but that sounds like a normal chevy to me. Good luck getting it figured out

On a note in regards to the issue at hand what codes is it throwing? Looking into the afm system I found that the afm lifters have been known to fail quite commonly, generally due to oil pressure issues or control issues. I don't know how you would go about testing it though.

You are over your head on this so take it to the shop. I agree with "Ford". Chevy in the last 10 to 15 years have been hit or miss.

It could be several things. The OBDII codes if you have a reader/scanner (cheap at Walmart, etc.) will help to identify where to investigate. I'll just share with you what fixed my issue which was very similar to yours. I pulled off the Vortec cover and left it off the top of the engine. I then pulled the electronic wiring harness that is routed around the top of the engine forward about an inch. Put a tie wrap around it to hold it there. Problem solved. (May have to remove the battery cable to reset the computer after doing this.) Sounds crazy, but worked for me.
