I took the truck in recently to a shop because it wasn't idling, and they found junk in the idle circuit solenoid. Cleaned that out and it runs better than ever.
I had been running without the egr hooked cause it would stumble but the mechanic hooked it up and it seems to be running alright now.
Passed 2 years ago with decent results.
Failed miserably this time.
Anyone have any ideas or suggestions?
Truck runs better than ever, idle has never been more solid.
Does it look like it's running rich?
Would a lean drop help get those numbers down?
I noticed this tech didn't put the truck on the rollers, not sure if that matters.
Any input would be really appreciated.
