how are your ignition wires.you didn,t say if had changed them,if not it could be a bad coil wire.i have this happen where a customer did his own sort of tune,replaced plugs,cap,rotor but not the ignition wires.turns out it was a bad coil wire.so i changed all the ignition wires because they were the original wires.vehicle ran great after wires were changed.hope this helps.
