Hi all , i bought my new dakota this week and the day ater the check engine light came on.
i only get one code p0306 Cylinder 6 Misfire Detected.

when the light is 'flashing' i can feel the cylinder is not working, i change the cap,rotor,wires and plugs because i was sure the problem was a wire.

one day after i still have the same problem ad i'm not sure what it can be? :huh:
ayone ever get a problem like this? any advice?

sorry for my bad english, i live in quebec
thanks
Eric

Motor size please?

Since you changed the cap, wires and plugs I would start looking at the fuel system. You may have an injector plugged or a loose connection on top of the injector.

Sometimes a vacuum leak will kill off a cylinder.

sorry its a 5.9 dakota r/t

today i check the compression and its ok around 165psi.
i got spark and signal to the injector..

when i reset the computer the engine is ok for a few minutes..or if i floor it for exemple 0-60 mph,after that the cylinder is not working.but i still got spark and the signal to the inj. :huh:


thanks
Eric

Not knowing how many miles you have on the engine all I can say is change out the #6 injector and see if that helps.

 

[rampagert]

the engine got 121000 kms.

how an injector can cause a misfire code?

If there is no injector pulse then you will see the code. The injector may be bad or the connection may be loose.
