2002 Fiat Palio 1.6 GTX
Idles extremely high sometimes. Compression ok. New crank sensor. Throttle body cleaned. No check engine light, however, sometimes TPS reports no voltage on OBD scan.

If it's an intermittent fault with the TPS sensor, then that will cause an irradic idle and no code. Check the wiring/connector first. If they're ok, replace the sensor.
