First thing unhook positive battery cable, unhook main cable on starter selanoid and small wire on selanoid (there may be 2 small wires) There may be a bracket on front of starter that has to be removed, and then the 2 main bolts that hold it to engine block and it should come out.

If this is "fly by wire" throttle, any misalignment between gas pedal and TPS will cause this issue. Failure of the gas pedal sender is so common Lokar company makes a replacement pedal unit that is much better than stock.

2008 GMC Sierra pickup. Driving and all of a sudden it shut off then turned back on; the doors unlocked then locked again. Now it won't do anything. Checked the oil and it was empty - no oil at

Running with no oil is death for the motor ( Seized). When the alternator stopped working because the engine stopped the door lock control opened the door locks as it said you were below the required speed to have them locked

When coming to a stop whiling drive my truck starts to mis-fire just for about 20 seconds or so then it goes back to normal idle. i've checked everything?

It's not misfiring it's sputtering. The torque converter is stuck in lock out mode and the transmission won't downshift until it forces itself out of lock out mode. Thus the sputtering. It's like trying to start a manual car off a light in fifth gear. There is a solenoid in your transmission that needs to be changed or your Torque Converter Controller which is a little module mounted in your dashboard need to be checked. Good luck.
