Was maf the only code?
If so i would start there. Unplug the maf and see if the plugs are corroded. They will be all green and gross. If its gunked up clean it.

and TPS is suppose to be at .38 (might be .48 I'm having trouble remembering at the moment) volts also. 4.6 is way too high! mine doesn't even go over 4.1 Volts.

Yep, .48 volts at closed throttle. It’s definitely not supposed to be set at 4.6V unless you’re measuring across the wrong two wires.
