Little background on the motor: just put on an LE street performer head, crawler cam, cold air, header with full custom exhaust, aluminum radiator and hoses, plugs, wires, cap and rotor all since last winter... It was running pretty good for a while just put the cold air on a month ago. One day I filled up the tank and got on the freeway and about 2 miles down the road it started cutting out real bad and I put the clutch in and it died. limped it home.on the way home it ran like shot but ever now and then it would run fine for a sec then cut out again..
Started Goin through things when I got home and realized it ran good cold but when it warms up it would miss again... now it has a hard miss cold or warm and at all throttle positions and RPM. So far me and my buddy have been swapping out parts trying to diagnose this thing and we've almost given up.
So far I've replaced the MAF, coil, igniter box, distributer, plug wires, TPS, fuel pump, fuel filter, catalytic converter and the injector resistor module, checked all wiring and vacuum lines.
I'm now thinking maybe injectors? I could really use some ideas on this thanks
