    Yep narrowed it down to TPS sensor as exu was throwing a code, I can’t adjust the tps to 0.5 it just won’t let me adjust it that far I can only get it to around 0.7. Once I adjusted it the code cleared itself and the car ran awesome for about 5 minutes before beginning to cut out and misfire at 4K again. One of the connectors on the tps the idle switch was snapped and upon fixing it and trying to plug it in the car only drives under load up to 2k before bogging down and not letting me accelerate or anything it just drops back to idle

    Bogging down at 2k is usually MAF.
    Given the age of the car and it's obvious electrical issues you're gunna have to inspect the loom very carefully looking for more snapped wires.

    Is the car lowered or has it been lowered before?
    Lowered cars have a nasty habit of rubbing through the wiring loom in the wheel arch, leading to all sorts of problems.

    Nope never been lowered still has the wheel well guards in, if i drive without one of the tps wires plugged in it will drive fine and boost amazing for a bit but eventually it starts bogging and misfiring at 4k if i plug the idle switch tps wire in the car just shuts off at 2k and goes back to idle

    It's probably worth running through the injection manual supplement, it gives instructions on how to test all the sensors.

    I'd start looking around to see what sensors you can still buy, given the age it's quite likely you've got at least one bad sensor.

    22630V5010 / 2263051E00 - Coolant temp sensor (ECU)
    2508089903 - Coolant temp sensor (gauge)
    2373185M10 - Camshaft position sensor
    2266035F10 - IACV (NLA)
