My 91 tsi randomly when warm gets a bad misfire as if it’s running on 2 cylinders, basically not drivable. When it happens also my wideband reads super rich (at 10.0).
After waiting for like 10-15 minutes for the car to cool off it will turn on and run fine until it wants to misfire again. I’ve replaced coil pack, spark plug wires, and power transistor but still have the issue. I’ve also took my injectors to get cleaned and tested and their good. No check engine light.
This issue has to be electrical because the car runs solid until that happens then have to wait for it to cool off, no overheating issues.
