-What MAF was installed? I hope not a C&L............those things are junk.
-Check for any vacuum leaks, a lot of what was touched has a line running to it
-Verify the IAC

I would take it back to him, he should make it right for you.

If car was running fine, why did you change all that? I would start with putting stock mass air back on.

Far as changing all them parts .....i figured that i will start to change out some sensor and do some upgrading .... not thinking that putting on new part's would end up like this . maybe it's not the new parts .just the mech .
