I am having trouble and need some guidance please. So far I’ve put a NOS TPS on and cleaned MAF with no change and don’t know where else to look. Car runs but will idle about 2,000-2,500 RPM and won’t shift till about 5k I need help figuring this out. The code P1121 is TPS inconsistent with MAF, also the duct work between the two is in good shape. It’s a 1997 continental with 98,xxx miles.

I would have a close look at the connectors and wiring.
The wiring is 23 years old. Over the years the engine heat can dry out the insulation on the wiring, causing cracks. Check all vacuum lines for cracks also.
A service manual will give you the voltage/resistance values to check the wiring and the sensors.
