I’m not quite sure what’s wrong it’s been almost two weeks and I’ve had it diagnosed showing it’s misfiring on 5 different coil but they’re all good and got new spark plugs and still runs reall rough like it’s to rich or too lean. When I give throttle it’ll just putter real hard or die?

Another thing when I reset the CPU with a jumper wire the idle will sound perfect and once it gets throttle it’ll revert to :poo:, exact same instance for when I swap out the PCM fuses so I’m not sure where to go from here? Please help

Since you washed the engine bay, you probably have water contamination of one or more coil packs, sensors, and wiring harness connectors. Check, clean, and dry all of them and hopefully that'll solve your problem.
Lesson for the future: Don't wash the engine bay.

Like 20 mins and then I ran it with a 370z down the highway, it was fine until I parked it for a few hours and then I drove it 20 miles and it died and hasn’t been the same since
