Is that the same drive cycle you have done? If not, try that and let me know if it helps. Thanks.

The specific drive cycle does not do anything.
Car has a bit of rough idle when warmed up, other than that it works fine.
Why would the computer module test say incomplete?
Expert:  Dan replied 1 year ago.
If drive cycle was not done as shown above it will show incomplete or if there is a problem with EGR system. Try to do drive cycle, if that doesn't help block off EGR to see if it runs better. If it runs better then EGR may be sticking open and need to be replaced before monitor will complete. Let me know how it goes or if you have more questions, thanks.

Block off the egr where?
Customer: replied 1 year ago.
I am not getting an P0400 code either.
Have done a similiar drive to reset egr, no code, however have not taken to smog place to retest.

Truck only has 82,500 miles on it, could it be an EGR sensor?

Hello Dan, are you still there?
Expert:  Dan replied 1 year ago.

Sorry about delay, I stepped away from computer for awhile. You will want to put a piece of tin/steal under egr valve to block off port. But first try and do above drive cycle as shown in link. Let me know how it goes, thanks.
