Not sure if i'm right here; if not please push!
Since a couple of days ago my Ram has been throwing out a cylinder 6 misfire. Not quite sure what causes the problem.But first i would like to explain what happend.
I was driving home at about 55-60 mph and all was fine, then going uphill on the highway the MIL came on and went back off.After a short while it came back on and stayed.The truck seemed to lose power and started to run rough.
So on the next day i read out the codes.P0300,P0305,P0306.
and deleted them.Truck still ran rough. And the code P0306 came back up, so i changed the Coil on cyl. 6 and now it still idles rough and shakes but the code is gone.Also disconnected the battery for a short while to reset the DME.Now i have a new issue. It starts blowing blue smoke on start and when i accel heavy.
Have no idea what the problem could be and hope for some hints.
