Question: After installing a sequential cng kit in my Alto k10, the RPM goes down to 500-600 at low speed when the AC is on and then comes up to idle. But when the AC is on at low speed the RPM goes down to 400-500 and then comes up to idle after 10-20 seconds. Why does this happen? The ICV, throttle body, spark plug and injector have been cleaned.
Answers: Since this vehicle has a sequential CNG kit, this is normal.
