Question
sdtom
My truck has started acting up. The SES light comes on and it does not shift out of 3rd gear. The trans was rebuilkt about 6000 miles ago. Then the light goes off and runs great when the light is on the motor surges and if I step on the gas and get at 3500 RPM it drops to 0 rpm and goes right back up. I did the codes one time and all I got was the 12 code. I started it and it run great for about 20 miles then I started it later and the SES was on again. I got 4 codes this time they are 32 EGR 34 MAP 42 and 45 both Oxygen Senser. This has the %.7 liter motor in it does anyone have any Ideal what is going on?
Thank you in advance
Tom
