5.0 Problems
Alright I have a 93 5.0 with a 97 Explorer bottom end, 255 Holley FI pump, 24# inj., Track Heat intake, 70mm tb, full exhaust, etc.
Ok I just put a set of heads, an F cam, 1.6 rollers, new lifters, and push rods. and if I sit in traffic for a few minuets my idle will drop from 1000 and will surge back in forth from 900-750 and will run like shit. When I start off I have to give it a lot more gas and the car will buck back and forth if I don't stay in the gas. But before when the car maintains 1000 idle it runs great and doesn't buck. Also while the car is running great, if I stomp on the gas and let off then the car will start bucking as well. The car didn't do this before the heads etc where put on, any help would be much appreciated.
--edit also the car is at operating temp.
