Bad idle problem

[TURBOV6]

The car starts and runs fine but you can hear a slight miss. When you gas it it sputters. No trouble codes.

I already swapped out the coil/module and the ecm.

I just recently did timming chain replacement.

sure you line up the gears correctly ?? installed cam sensor correctly, bang the stock MAF around when removing/ installing it(thats a no no) vacume lines all reconnected correctly ?? whats the scanmaster say for IAC, BL ?? O2's moving around alot or steady??

check plugs/ wires again and do a resistance test on the coils.
