need help, p0306

[nickw226]

I just finished up a egr delete, cac pipe, new used intercooler, coolant flush, ccv mod on my 230k 6.4. Truck fired up great and about 30 seconds of idling it just started missing and smoking out of the tail pipe a little more than normal. Check engine light code p0306. Misfire detetected in #6 cylinder and inbalance code on 6 cylinder as well. What gives??

Sounds like the #6 injector is starting to hang open.

It runs great now. Im not sure what the hell happened. Either there was a piece of debris in the intercooler that got hung up in #6 cylinder or the fact that i drained some fuel out of the fuel cooler schrader valve while the truck was running. Im not sure. Does the injector hang up and then go back to normal when it starts to go??

It's possible for an injector to hang up then act normal. If it starts acting up again, I would suggest changing that injector before it causes damage.

will do. It seems like I have some fuel in the oil as well. With 230K on injectors im sure its time for a rebuild
