Okay, so i made a post a few days ago about my project car without much info. I figured the best thing to do is make a new post with more info I have gathered. My problem is that i have a 2000 2.5 RS with an 04-05 STI motor swapped in it, and itll start and idle just fine, but when you push the gas pedal it will not rev. I got my hands on an Actron scanner and got some info.

The car is throwing a P2109-Throttle/Pedal position sens A Minimum Stop Perform....
Maf flow GR/SE-3.69
Abslt tps%-15.6
ST FTRM 1 %-0.0
LT FTRM 1 %-0.0
ST FTRM 3 %- -100.6
LT FTRM 3 %- -100.6 (arrow down)

From this im getting the sensor is obviously bad, but im not sure where the sensor is..? And the Maf is bad and needs replaced. Other than that im not too sure about the rest of the numbers and would appreciate any info on them, and the position of that throttle sensor would also be appreciated. Im also open to other ideas if anyone has any on what to check in addition to these 2 problems. Thanks.
