my 94 will missfire when you floor it in 2nd, 3/4 throttle in 3rd, half in 4th and anything over 1/4 in 5th. this is very weird and i can't find out what would cause this. this miss is the NGS says that the car is comanding rich but the O2s both cycle back and forth through .45 volts regularly. any help would be apreciated.
