1st there are 3 codes stored. Misfire cyl 1, 2 & 3 it misfires on 3 about all the time it has ha dall thge plugs, coil packs changed 2 times in 5000 miles. After chaging evrything it will do ok for about 75 miles or until I put it in hard excel. When I put it in hard accel, as in passing gear the motr will get to about 4000 rpm and the engine light starts to flash and the motor slows down. It will not pick back up uintil the light stops flashing. When I pull the plug on 3 it is wet with gas. What is going on?
