I just replaced the injectors on my 03 LB7. I am not a diesel mechanic but I have done a lot of engine building and mechanical work. I studied every forum and tried to make sure this went well.

I used OEM injectors
Replaced the cups
Used loctight 272 on the tips
Torqued every bolt to spec
replaced the fuel lines


Everything went well. Truck started fine. Idle is good. No smoke at idle.

Temps all good. No codes. no leaks.

When I test drive the truck under load it is smoking bad. I only drove a mile or two. It has low power and a louder than normal diesel knock.

I guess I will need to take it to a shop so they can check flow rates and pressures. Is there any thing else it could be.

Truck ran fine prior to injectors but was making oil and injectors had about 90K on them. Truck has 184K.

Truck does have a bully dog tuner. I am assuming the tune stays when both batteries are unhooked. If so it should have the same tune as when I started.

Please tell me there is something simple that I have missed.

Thanks for any help.

This all sounds like a bad injector which would be very unfortunate.

yeah you wont have any codes if the injectors are junk or if you had a boost hose off. do a search about pensecola and you'll see. From the sounds of it they throw new nozzles on and send them out and new injectors or some crap.

They told me these are not their rebuilds. They said to eliminate any worries its better to buy these OEM units. I am actually going to be in Pcola next week. I plan to make a visit if I cant get this resolved.

The smoke was white and seemed to diminish the farther I drove. I didn't leave the boost hose loose.

Do us all a favor and burn that place to the ground while your there:villagers:

as many injectors I've read were junk from there and there still in buisness, they can't be refunding money. Sorry man but now u know Bosch reman or exergy.

is there any way you can intercept your cores and then dispute the credit card charge for not sending you what they claimed and that you had problems with what they sold you?

Is this a California truck? It sounds like an EGR problem possibly.

There is where they lied. Original bosch OEM injectors don't exist anymore just the Bosch OEM remans.

You sure about that I just bought " new Bosch injectors" from exergy or so I'm told
