2007 335i, P100088 last 7 of vin. Car is stage 2+, full bolt ons if that is relevant

The car idle is bouncing up and down constantly, and there is no response from the throttle pedal, but when hooked up to diag to read live data, I can read the throttle and seems to be working but the tps says that the butterfly valve isn’t opening when I step on the throttle. Tried a brand new throttle body, checked vacuum lines and connections but can’t find anything broken or disconnected. Can anyone shine some light? I’ve also tried resetting throttle adaptations both with mhd and by holding the gas pedal for 30 seconds

Have you checked the ECU box? I had the exact same problem with some of the same codes but mine would stall/cut out after idling for a few seconds. Thought it was an electrical issue at first but I decided to check the ECU first, Opened the ECU box to find a lot of water.
