Yes I do have MAF on the truck. Here is a little more information. On initial start up, I have to actually press the gas pedal to crank the truck. Fuel pressure is 58 to 60 on the rail. Again as it is idling, if I accelerate the motor, when it comes off of acceleration it idles rather low like it wants to die and the MAF sucks ev en harder(louder) during this low idle. I also took the vacuum hose off of the regulator and no gas was in the line. The only code that I am pulling is P0650 MIL. The motor actually acts as if it has a dead miss to it. During acceleration, it is not a smooth acceleration, not a responsive acceleration. Lastly, for the heck of it, I pulled each coil wire off while the engine was idling and damnest thing, the motor did not respond it. Not once did the motor act like it wanted to die or miss worse. That was strange. Any suggestions??
