If I baby the throttle, engine runs fine. Give it too much and it misses just like a bad cap and rotor. The cap and rotor I took off only had 1000k. Replaced it anyway. Not the problem. I have changed plugs, plug wires, ignition module, retimed it, fuel filter, ohmed out the coil. Me next two options I can think of would be either the halls effect or the ECU. Anybody ever run into this ?
