I have a new odd issue with with my truck. I had an EGR Delete installed on my truck. This delete kit removed the EGR Cooler, replaced the passenger up-pipe and left the EGR in place and connected to the harness. Before the delete the truck was running fine. Now I have a strange surging and occasional stumble. It has died a couple times when at idle, in-gear either at a stop, or rolling through a parking lot.
The surge issue feels like the throttle is being stabbed, but is almost instantaneous. IT seems to happen more when the engine is cold, but have had it happen after a 100 mile trip.....
I do have a check engine light with the following codes:
P006A - This is some kind of Mass Airflow Sensor issue
P0401 - EGR Flow Insufficient
P0404 - EGR Control Circuit Range/Performance
P0405 - EGR Sensor A Circuit Low
P2285 - ICP Sensor Circuit Low
I am at a loss what at is causing the problem. The Fuel, Oil, Oil Filter, and Fuel Filters have less than 5000 miles on the, The FICM was repaired last year. The Mass Air Sensor has just been cleaned. The wire harness was checked over and there is no wiring issues. Hopefully someone out there has heard of this, and knows what the fix is.
