Number 4 cylinder misfire
Could anyone tell me what could cause my engine
to miss under a load or at mid rpm range around
3000rpm or above followed with massive power
loss a few seconds into it ?
it throws a #4 cylinder misfire code p0304 .
I've give it complete tune up plugs,wires,distributor,
distributor cap,rotor button, changed maf sensor
,maintains 50psi fuel pressure while driving
,checked compression it seemed to be fine also at
around 150psi
