I removed my injectors the other day to temporarily fit them in another car, which it turned out they werent needed. When i was removing them, some / all of the fuel rail petrol dripped into one of the cylinders (furthest left if standing in front of the car). All happened quite quickly to do anything about but thought it would just evaporate or burn off...
A day later, i refitted the injectors and the car spluttered to a start but was fine once the fuel rail had filled up with fuel again. I drove very gently for about a mile or so until a hill forced me to use a bit of power. When the boost came in a bit stronger, about 2700rpm, it started to splutter and misfire :-(.
I crawled back the house when the engine warning light came on and then started to flash (only under power). So i plugged in one of those cheapy fault code readers and it came up with cylinder 1 misfire code.
Ive changed the plugs
swapped round injectors
i'm about to do a compression test to confirm/deny the worst!
I'm guessing ive upset a sensor rather than done anything serious but if anyone has any suggestions on what to try next im all ears!!
