When i let off the gas pedal or try to maintain my speed I notice that my throttle position picks a value higher than what it really is. At the same time my MAP jumps up in PSI and my AFR fattens up. My RPMs stay the same but it kind of slightly bogs the truck down. If i accelerate it will clear itself up. Within the last year i replaced the pedal and the throttle body trying to resolve this issue and eventually it went away on its own. Now it has come back with a vengeance. I replaced the MAP sensor a couple of days ago to affect. Anyone had any similar issues?

Oh and Hello and Thank you.
