I think this is unrelated but a couple of days prior to the first reduced tank of gas I got, I cleaned the air temp sensor (connected to the air filter housing) with WD40 and also sprayed a little WD40 on the throttle microswitch.

However, the air temp sensor was checked by testing resistance while blowing at the sensor.It varies and the values are within spec compared to a new one.

The microswitch also has resistance values when closed/open depending on which terminals you get the readings from, so I guess it is working.

Hope you guys can help me here.
