Hey all. So my 91 mustang speed master heads 190cc. X303 cam, megasquirt 2, msd6al. 42# injectors.
I have a misfire and a popping noise. The popping is intermittent. But the misfire is pretty consistent.
I replaced the plugs (they were black/soot covered) and cap and rotor. The wires are new last year as well as the coil and tfi module.
I have in wire test light. It shows good spark most of the time then it dies down and will then come back. As the motor has a hard time idling because of the xcam (low vacuum) I'm not a fan of it but will replace it when I get the budget to do it.
I have checked timing and I don't know where to from here?? Any help is appreciated.
