Hey everyone, just looking for a little advice, I’ve got a 98 e430 that runs flawlessly up until you give it full throttle, cel blinks and it misfires so bad it sounds like a tractor. Just turn the car off and on again, and it works fine again. Recently replaced plugs n wires, I just ordered a maf sensor just in case. Any help is appreciated, the car has been in the rust belt it’s whole life, and it’s running up on 400k miles, so I know it’s not gonna be perfect haha

    A few times, its always a bit different each time. Random misfire, cylinder 7, cylinder 1, and secondary air injection system. Next time it was random, cylinder 5, and 3.
