Running winaldl as a diagnostic check, could some one confirm that the log winaldl produces show tps voltage.

The log reports -1.5 at idle and varying amounts with increased rpm some examples.

3475 rpm 20.9
2025 rpm 8.2
2250 rpm 16.9
3375 rpm 25.5
4025 rpm 11.3

All very varied and not aligned either, high revs low voltage and vice versa.

Should voltage range be between 0 and 5 volts with idle being around 0.4 and wot around 4 volts.

The engine idles very irratic

Thanks

Start with the key on engine off scanner connected and scanning. Look for the TPS voltage, not TPS %. Adjust the TPS to scan about 0.5 - 0.6v. Then slowly press the throttle watching the voltage reported. You will only get an update a second so do this really slowly. Watch for the voltage to increase smoothly with no drop outs.

If the TPS passes the two above tests you are good to go.
