I need some help, I followed some instructions on how to remove the injectors, take them apart and clean them. I did this put truck back together, started it up, had a bit of a rough idle.

Not excessive smoke that I could tell. Not bad, but also had a bit of a knock to it.

Drove it to work, came back home, tore it apart, to double check everything.

Double checked #3 injector, feed tube torque, etc, that was the one I just started with to see what would happen. Took injector back out, back apart, cleaned reassembled, etc.

Put it back together, started up truck, smooth for a few mins, no smoke, anything. Running good, until.... Drove it around the block, was doing just fine, no knock or anything, until I hit the throttle a little to get it up to speed 55MPH, started feeling a miss, especially, when torque converter locked up. Throttle began to stick!, had to shift into neutral to slow it down. Smoking black smoke pretty thick.

Once in neutral RPM's came down normal put back in gear, hit the gas 1/2 throttle, throttle doesn't stick but get the knock still.

Hit the throttle with moderate pressure, it sticks at around 1600-1800 RPMs shift to neutral, back down to regular RPM's.

Got back into driveway, rough idle especially in gear.
Truck was running worse than previous day.
Took apart the entire top part of rest of injectors, and checked, all working good (the part under the solenoid).

Has knock almost does sound like diesel running on fumes, or starting fluid.

I have no idea what to do next, almost ran into my garage with that throttle sticking. sheesh. Take out the other injectors and try to clean them again to make sure?

**update, took two of the other injectors out tonight, did a test run, still the same. Got just a couple more to try.

Anything I am missing here, something else I should try? Dirt get somewhere maybe, making something stick? I am just frustrated, don't know what to do next.

 

Take one injector to injection shop and have them test it. Or "all" for that matter.
The black smoking sounds like a leaking injector and making more power than computer can control. Did you forget the copper shims. They are not reusable according to FSM.

 

Double check the wiring to the fuel control actuator on the CP3. The FCA will ramp to maximum pressure without a control signal. Maximum pressure will cause knock, black smoke and a throttle that acts like it is sticking.

 

i guess warranty bit the dust when you tore into it?

 

same thing happened to mine and took it to Dodge and it ended up being the sensor. Took care of it and runs great now.

 

Just wanted to update this, took to mechanic, did individual injector shutoff, mechanic said #3, changed #3 cleaned nozzle on #3 truck runs perfect again. No other damage done, thanks for all the help. Don't try cleaning your injectors, I don't care what you read. Thats all I can say, and if you change nozzles, do it in a super clean workspace.

Truck was well out of warranty period, 120K on it.
