Not able to rev past 6k in neutral or past 5k while driving
Just like the title states, I can only rev up to 6k while in neutral and up to around 5k while driving before it feels like I hit a wall. I have just changed my distributor, cap, rotor, and coil. I also have fresh plugs and oil. I throw no codes, and do not have a CEL. Could this be a clogged cat? I banged the catalytic converter but did not hear any rattles. I drove around with the front O2 sensor disconnected, and that made no different either. I am at 15 degrees as far as timing. Any suggestions guys? I really want to be able to rev to redline again Thanks !
