Slight mis-fire at partial throttle...until I disconnect air temperature sensor

Hi,

resistance does not change over vacuum. It is always the same. Transformation of input signals from ECU changes. That is why it is also called VLT - variable linear transformer.

Understood that the vacuum has no effect on the sensor. The testing I did was in different temperature water and I saw the resistance change. I matched that with a chart (that I likely found here ) and it seemed within reasonable spec.

The popping when I re-connect seems to be throughout the throttle, not just when slightly opened. It also seems to idle a bit more roughly. All of that goes away when I disconnect the incoming air temperature sensor on the air filter intake.

Hi,

that means you engine runs slightly too lean. Sensor removal increases mixture on warm engine by 10-20% . That is of course not a real solution. You need to find out what is wrong. Exhaust gas measurement per cyl might give a good hint.
