Napablank ko din innova ko na 1st gen. Had black smoke problems before. Nadala ko na sa casa twice. First time, they just cleaned the exhaust system. The second time, they "replaced" the egr daw... Still black smoke after a few months... Visited central diesel in quezon ave...they replaced 2 injectors that according to them has abnormal spray pattern... Spent a fortune... After a few months, black smoke returns.... I brought it back to them... They checked the egr and injectors via obd2 scanner...no faults found... They serviced/cleaned the egr without charge...after more than a month, black smoke returns... I researched in sulit/olx and found someone selling a stainless steel blanking plate. I bought one and had it placed by my suking mechanic...He told me it might be a turbo problem... We install the plate....lo and behold...black smoke gone...meron pag nasa 3-4k rpm pero not as much as before. Dati parang pusit worse than smoke belching buses and jeeps.to guys out there having doubts on egr blanking...it will save you a fortune and lots of hassle like i experienced. If i only knew then...
