My 96 k1500 5.0 is idling rough, and popping out of the exhaust. It starts fine, seems to rev ok. It's got a new coil and ignition module. I checked the rotor it turns fine no jumping or skipping. The only thing I haven't done is check where the rotor is pointing at TDC. Truck has 256k mi so i guess it's possible the timing chain jumped a tooth. But from what I've read that usually comes with hard starting too, but that's not happening.
