Got a p0121 code and put a new TPS on but it still runs very bad and the same code keeps coming back.

I attached the testing that we need to run through for this. Unfortunately the sensor is only one of the possible causes. The other include wiring or a PCM issue.

Let's run through this test and see what turns up. Let me know what questions you have with this. Thanks
