2003 GMC Sierra V8 Four Wheel Drive Automatic 145000 miles
My truck (a duramax diesel with a programmer installed) has recently started sending out trouble codes and acting really sluggish if I push the accelerator to the floor. The codes are P1093, p1621, p2227, p2228. I originally thought it was my transmission going bad but with the codes starting to come out im not sure. Do you have any thought on the matter?
