My vezel 2014 after putting on scanner is giving the following errors P0301 MISFIRE with all cylinders PIC also attached
The workshop suggested to change the fuel injectors which is costly any other solution like a patent workshop whom can clean the injectors in lahore or Islamabad

You need to find the reason for the misfire. Not just assume. Try @syncview in Lahore. Osama car care I believe.

Workshop guys already told me to put new injector set kabli is like 70k

[affanhaq94]

Is there proof of their diagnosis? Or did they just say it needs new injectors?

Why not have them removed and cleaned on an injector machine rather than buying replacements to see if that helps?

Do some reading here. It may help give you some information. And again, the only codes stored are misfire codes. So you may want to ask your mechanic if he confirmed the injectors or is something else causing it? Did they check the spark plugs? Etc.

Honda Vezel Injectors carbon buildup & Engine De-carbonization

I have a honda vezel 2013 model with 60k km on the odometer. Last weekend i decided to to have the throttle body cleaned up with the oil change. For some reason i decided why not to open up the injectors and see their condition even though there was nothing wrong with car fuel delivery system / acceleration / start-up etc. On opening the injectors i saw a large amount of carbon deposits on all the 4 injectors nozzles (See picture below) which i got them cleaned using a carburetor cleaner.

These codes can be caused by a lot of other issues.

Do the trims drastically change at fast idle?

Does this Workshop own the cleaning machine?

Workshop doesn't have a cleaning machine for high pressure injectors
Didn't notice the trims but I think they remain same in idle
The error lights come up after 2,3 days after every reset , so far I am driving with this jugaar
When rver the error lights come up just reset the vehicle with battery terminals removal

Looking to visit some work shop with advances Injectors cleaning machine

You need a deeper diagnosis, injectors clogging to the point of misfires will show a lot of other problems too.

What is the commanded duty cycle of the injectors at idle, fast idle and also driving?

Also test the AFR sensor output to see if it's not malfunctioning, cross check with the equivalence ratio to confirm.

Did someone try cleaning the catalytic converter or the exhaust sensors in the past?

[pwuser164241681921]

Catalytic converter was serviced last year almost 13 months ago

Will check them and discuss it with workshop guy in chakwal..
