AOA all PWs. i had been a silent reader of PW forums since years and benifited from vast info available here. right now i need special attention of experts to help regarding suzuki liana 2007. history is as follows
-engine changed a couple of years ago with japanese M13 engine
-dont remember whether the ECM was changed or not (even dont know whether its required or not)
-since then car is hesitant on acceleration and doesnt climb easily (even on 1st gear).
-mechanics changed clutch assembly 3 times and tunning stuff many times.
-car starts easily and never stopped at all.no check engine light. even sometimes i feel it ok on plain roads but turned out to be same on climbing.
-catalytic converter removed and exhaust checked.
-no check engine light however egr sensor is not connected and blocked.
now as i mentioned earlier i kept on driving the car for two years because its not a daily runner and used for city driving with my family. furthermore fuel economy wasnt bad at all (12 kmpl in city). now since last two weeks its fuel economy is getting worst. 02 sensor is recently changed (Check engine light goes off) and the car seems like it was before (no idle problem+ same hesitation on acceleration) . but the fuel economy is still getting worst (30kms/ 1000rs). no leaks detected
now i want to resolve the issue (hesitation + economy) and need you ppl. should i go for engine change?? or anyleft to do?
im really sorry for haphazard post.
