on the way home from Hot Springs yesterday, I had the cruise on at 55mph. half way home, when starting up a hill, it would go down to about 40mph, drop two gears, the boost would go from 2 to 18-20 almost instantly, and the egt's would jump to 1200. It would accelerate like crazy. Next hill would repeat itself.
Codes:
P0101: Mass Air Flow Sensor Performance
P0401: EGR Flow Insufficient
P0404: EGR Open Position Performance
P1404: Exhaust Gas Recirculation Closed Position Performance
P2228: Barometric Pressure (BARO) Sensor Circuit Low Voltage
I am not egr blocked, pcv rerouted, or anything. I have a Banks Six Gun, Banks Monster Exhaust, and Banks Cold Air Kit with Super Scoop.
I am about to start taking the top end stuff off to see if or how much soot build up I have. I cleaned the Mass Air Flow Sensor with the proper cleaner, and no, there was no oily buildup on the sensor or in the tract to the turbo. I will also be changing the fuel filter. Any suggestions on what could be the cause? I have read that the first three codes will come up with higher flowing intake and exhaust mods, but all of these at once...
I leave for vacation in 11 days...
THANKS!
Mark
