Hi guys,

I have a Mini R50 2002 and I have the Code P0301 Cylinder 1 missfire detected. I bought a new plugs, wires and coil pack, but the problem is still here.

It happenes only when the engine is warm and only when Idling. Also I have a small (1cm x 2cm) hole in the upper side of the airbox (just see through the side of the air filter).

Some help please?

Ok, I will repair and then I let you know. Now I read that could be from the bad coolant temperature sensor or Thermostat too. I fix the hole first, thanks.

 

Ok Ive just put the duck tape over it and also I found the Intake hose broken, so I put more duck tape. Now I cleaned the Throttle body and its better, but I need few days for testing it.
