Truck seems to have a slight miss

The truck seems to have a slight miss. It is very noticable at idle, not so bad when cruising, but very noticible under load ( like when going up hill or while towing).

I have been running 2 stroke oil in the fuel, and use power service every other fill up or so.

The air filter is pretty clean, and it has a new fuel filter on it.

Has a lil smoke when its first started in the morning, and smokes black underload.

Any ideas?

Re: Truck seems to have a slight miss

You should try to do an Injector contribiution Test. That way you know which injector is weak. It might be a bad connector on that injector or it could be worn a little compared to the others. I have a couple that run like crap when cold . I will be inserting Stage 1's very soon . . .

Re: Truck seems to have a slight miss

If you can't get the contribution test done, listen for a loud clicking on one side of the motor. You could always remove the valvecover on that side and check the injector oil spouts for pretty much each injector discharging the same amount of oil. If one isn't discharging much, it could have a loose poppet screw under the solenoid (i've had the happen multiple times), or even a bad solenoid. Cheers!
