Hi all, new to forum. i have an 1988 rs that i swapped a 1988 tpi 350 from an 88 iroc into. runs ok but im throwin a MAF burnoff relay code, i used a painless wiring harness and have the correct computer and prom. the car runs really rich and hesitates when u hit the throttle sometimes. also it will surge at idle sometimes. any ideas why??

 

its hard to get a response on this site! but just out of curiosity was the engine you pulled out of the rs a 350? if not you will need to have a 350 chip!
