Ok well we have a new cat OE replacement. No exhaust obstructors. Timing is right on the mark. Fixed intake bypass. So now there is power but it still misfires and stalls out when you come to a stop or let the revs drop. We checked everything that the Helms manuel says. Dont have a scan tool. And I never checked into the valves. ( I dont think that would cause it to misfire) Idle air valve seems to be doin its job. Only other thing the Helms manuel says is that it could be the fuel pressure regulator but need the tool to check the pressure.

So what do you think?
