| on the 2 cylinders that aren't firing, pull the plug wire/coil pack and put a spark plug in it, hold it close to a ground like the frame. crank it a few times and see if you have a spark on those 2 cylinders. if you do, then i'd just say you have 2 clogged injectors. i would think that's all it is, since it ran fine before. you may have churned up some old gunk in the tank that is now in the injectors. if you are brave,you can swap injectors and see if the problem moves. if it isn't firing, swap the coils to the other cylinder and see what happens.
are you sure it's fuel in the exhaust and not just condensation from not being used? |
