It idles great drives ok has a little stumble and a few buffs of smoke at the top of 1st 2nd and 3rd gear driving like an old man.If i drive it like i stole it no problem no stumble.
If in park engine at temp and i stand on the pedal itll smoke like a freight train out the exhaust and really doesnt wanna go higher than 2500 rpms.

smoke is white not lossing an OZ of coolant,Swapped out turbo with a new one no change and no codes Cleaned EGR valve no change/Replaced EGR no change Changed air filter no change

Checked FICM voltage appears fine 47-48volts.Batteries run at 13.8-14.2 volts.

 

I'm thinking you have an exhaust leak into the fuel rail (failed injector crush washer) maybe. Pull the secondary fuel filter lid, disable the fuel pump, and have somebody crank the engine while you watch for bubbles. Also, check your fuel pressure.

 

can i unplug each injector run it up to 2500 and rule out which ones it isnt safely?Or do i just pull all 8 and install new seals????

 

anyone else wanna chime in?

 

Pulling one injector at a time should help you rule out an injector problem. Start pullin one injector at a time and see what you see.

 

Pull one injector at a time and mat the pedal and see if it smokes at 2500rpms?

 

bump for more opinions

 

If you have combustion leaking into the fuel rail it can affect the whole side. The proper diagnostic would be to pull the secondary fuel lid and check for bubbles while cranking. IF bubbles are present then remove each fuel line and do the balloon test to narrow down which side has the leak. That will save you some unnecessary labor and cost. If/when you have made the determination of a leaking injector then you can pull them one at a time and the offensive member will be readily apparent. The puzzling thing is not having any contribution balance codes, not losing any coolant, and only runs up to 2500 RPM's. I'm still wondering about the fuel pressure too. What are you code scanning it with?

 

Snapon solus to read codes

under load itll run up over 2500 itll stumble and puff a little smoke.If i matt the pedal in nuetral or park itll hit 2500ish and smoke like crazy and stuggle to go higher

fuel pressure is 65-70
