Today when i was trying to rev past 3000 rpm, there was a sudden thump and the check engine light came on. Stopped the car and started it again, the light is still on. Then I started the car and proceeded a bit slowly. Felt everything normal but the check engine light is still on. Upon reaching destination found this in the engine bay. Some fluid got splashed in the engine guard plate. When we were testing after remapping from wolfmoto, same thing happened then. Rajeev then cleared off fuel rail pressure warning and after that there was no problem till now. My OBD cable got damaged and not working to check the error codes. What could have gone wrong?
