Have problem with the local Honda Jazz Manual 1.3 when running at RPM below 2K.
Note : Idling is normal (TB & IACV recently cleaned)

Pag andar mo from 1K to 2K rpm the car jerks/stalls ("kumakadyot").

Tried to have the coils inspected and they were replaced with surplus ones that are
working na. Also spark plugs where replaced na din.

Saan kaya nangagaling ang problem?
Any recommended shops QC/Manila that are experts in diagnosing this problem beside
casa?
