Help Me!!
My 1991 tsi has been acting up lately and was wondering if anyone could help me diagnose the problem. My 02 sensor and wire i diddnt realize were slowly melting even on the heat wrap and eventually failed and i threw a check engine light, it started to run really poorly, but only after 20 mins or so of it starting. So i temporarily unplugged the sensor, the car instantly ran better, and the engine light went away, but sure enough, right when it gets up to operating temperature, it starts to, how i would describe "bogging out" , it even acts like an IC pipe fell off (which it did not), but i was wondering if it could be an ECU problem, maybe the fuel injectors are failing, idk but i need help becuase it is my daily driver!
