Good morning and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

What codes are setting? Do you have a P2262 code and have you had the ECM updated recently?

When you drive it and press the exhaust brake button to engage it, do you hear the turbo whistling when you slow down and when you speed up does it feel like it has full boost? When you had the actuator off did you move the slider ring back and forth stop to stop?

Customer: replied 1 year ago.
Exhaust brake seems to work properly and the slide ring moves easily back and forth.

When did this start, and have you had the 65k emission cleaning performed? Is the air filter in good shape? Is your tailpipe black or clean?

Customer: replied 1 year ago.
the only time this happens is when the out side air is worm,in the morning when the temp,is in the 40 and 50 deg. the truck
runs great with no smoke. This started about 30 days ago the air cleaner is clean and the tail pipe is black. The truck has 100350 miles on it. I have it serviced on a regular basses.

With a black tailpipe your DPF is busted and it will need to be replaced.. Do you have a programmer on it or is it stock?
Customer: replied 1 year ago.
I have a programmer on it.
Customer: replied 1 year ago.
What is a DPF ?
Expert:  -Brad- replied 1 year ago.
Ok if you have a programmer that deletes the DPF then a black tailpipe is ok. The DPF is the diesel particulate filter. When it starts smoking black what is the fuel rail pressure.
Customer: replied 1 year ago.
I do not know what the rail pressure is, My mechanic did replace the fuel pump when this first started and he said the rail pressure was good.
