I did the throttle body swap. I have a 2200 engine and put in a Quad-Four throttle body and the Throttle Postion Sensor of that ENGINE.
My throttle postion sensor from my car would not fit, so I used the one with the throttle body.
I use a scan tool to monitor the signal from the sensor. I am getting a working signal from the TPS. It is at 0% with no throttle, and slowly works it was up to around 99% as I put the pedal close to the floor. The problem is that about 2 inches or something till the pedal finally hits the floor, the TPS will read 0% but the throttle is completly open.
If you ask me, TPS reading of 0% at WOT is a bad thing.
I would think that my engine proformance would be effected, as the TPS controls the engine behavior. Such as Ignition Advance, which shows advance of 40-45 (the reading) at about 80% throttle, but 23 (reading) at WOT. Just for information, the Advance is reading at around 15 durring idle.
Any Suggestions...

OnDemand5.com.... I found a spec for the throttle postion sensor. Voltage to be from 0.35v-4.65v. I assume the higher number is WOT, so i could just hop in and check with a fluke meter.
