-- it is costly, 15K-20K depending upon your rapport with the shop

. Hope you have a friend who knows someone from calibration shops para hindi ka maloko, ma-refer ka ba ng maayos. Yung iba kasi sinasabi na calibrate na agad, but a simple clean of the fuel system lang pala will do (check fuel line, replace fuel filter, check fuel tank for foreign debri or rusts, water contamination). Or gaya nung sa 2nd hand Strada ko na 4d56 din, nozzle tip lang pinalitan. Medyo mas mura yun, I just forgot kung magkakano, 2006 pa eh. Pero sa speed mo kasi na 80kmh max, medyo malaking problem yan. L300 FB kasi ng officemate ko ganyan naging problem. Palit ng surplus injection pump at P6.5K na lang kesa calibration dahil P18K quote sa amin noon eh. Dapat pa-check mo na agad yang ride mo sir, baka kasi slide na rin kasi ang transmission mo kaya the earlier na mapalitan, the better. Baka lumala pa yang problem eh.
I hope makahanap ka ng matinong shop para hindi doble expenses mo. One time repair lang at ok na.

Taga-saan ka ba sir, para may makapag-reco ng autoshop na ok at malapit sa inyo.
