Re-checked this morning with no air passing through the AMM I have approx. 15 kHz and at tick-over I have approx. 4khz so this meter does indeed work in the reverse compared to other digital AMM I have checked in the past. Question is is that OK, live data is confirming my results but no fault codes are logged and the car billows black smoke!
Help!!
