My 5.0 has a bad idle surge on cold starts. Revs up to 2 grand and as low as 500 and sometimes dies. The motor has trickflow heads and lunati cam. Also has egr delete and new throttle body, stock mass air and injectors, and the smog is still attached but all the lines have been removed/plugged off. Where can I start looking to fix this? My car is LOUD and I leave to work at 7am and my neighbors probably hate me!
