G50: Throttle Position Sensor Problems - 1500 RPM + when set at .44v

[lino]

I have had a problem with my TPS for some time now. If I set it to .44v the car idles at 1500+ RPM. Currently, it's set to .20v to have the car idle at 650 RPM. I recently replaced my TPS sensor and MAF with new oem parts and both air and fuel filters. Where to go from here?

Lino- the TPS, AAC, and base timing must all work in unison.start with the 0.44, then crank down the AAC screw until you are at about 650, then make sure base timing is at 15 (note that you may have to tweak the aac--easier if you unplug the aac/ecu control while setting up the base timing), then with timing set, and 600 rpm with harness off, plug back in the harness and you should be close on aac duty. obviously better if you have the consult, then you can read aac directly.

Lino check the timing by using ECU talk. Change the timing offset in the ECU talk .ini file (Make sure it set to -30).

And I told Lino to set the TPS to .44 volts and he did so. He started up the car with the AAC valve untouched and the car idled at ~1400 RPMs. I also told Lino to clear the "Self learn" (For the fuel ratio) and he did so with no change.

I don't remember what happened when I told Lino to adjust the IACV with the solenoid unplugged.

Could a bad O2 sensor cause this?

Lino's throttle body screw are untouched too.

His intake is also clean.

Base timing must br read using a timing light
