Running down a miss.
Ok, I am a bit stumped. I have recently within the last 4 months replaced the plugs (TR55'*), Belden wires, Denso O2, upper and lower intake gaskets, pcv, BCS, swapped the BCA, replaced both belts, and added the Magnaflow cat. I have also swapped around coilpacks with three JY ones I have, cleaned the ICM, and checked a few times for vacume leaks. I still have a miss that is a bit of a rough idle and the bucking in 4th and lockup. It seems to be gradually getting just a little more bucking as time goes on. Any advice on what else to try? Maybe the ICM, or PCM?
