make sure your TPS is adjusted properly (.45) and gets a stable voltage. Pressure check your intake for air leaks after the MAF. You probably have an air leak.

Big thing to check too is the IACV and make sure its functioning/ has power and such connected to it properly. Grounds should also be checked over to make sure they are all properly hooked up. lastly you should do a boost leak test and fix any and all leaks, they will wreak havoc on your drivability if you dont.
