misfire at idle and while driving
Hi, i have a 87 iroc that originally had a blown up 305 LB9 motor in it so i never did test drive it before i did a 350 swap. So i got a 350 from jasper and installed that with a new 700r4 from GM. At this moment i replaced the injectors with 22lb design III from southbay injectors, 350 knock sensor, 350 electronic spark control module, and a new ECM. I am having trouble with a misfire at idle and i slight misfire while driving (you can barely feel it). What can i do to resolve my problem? This has been going on since i replaced the motor.
