I have a 98 V6 4.0. I recently replaced the Throttle Position Sensor and I am now getting the following codes.

P1121 Throttle Position Sensor Inconsistent with Mass Air Flow Sensor
P0122 Throttle/Petal Position Sensor/Switch A Circuit Low Input

It idles pretty rough in park, but when in drive or reverse it drops. Also it does hardshift a little bit (automatic).
Any thoughts on what to do?
