Doc Diesel,

My 97 Pajero emits black smoke when revving. Regular naman ang oil change ko and PMS. It's never been overhauled nor calibrated.

How much do you charge for diagnosis, calibration or overhaul? May discount ba kung taga-TSIKOT:wink: You can email me at wdfabian*yahoo.com.

Saan nga pala shop nyo? I work in Makati and I live in Cavite.

Thanks in advance.
