I have 99 4.0L OHV with a precat after each manifold then the Y and then two more cats.
I believe my cracked heads caused fuel to dump into the precats and clog them. truk runs ok but no top end power. no cels.
My question is if my precats are hollowed out, will the back two cats be enough for the engine to run OK ?
And will I pass CA emissions ?
