Engine Performance problem
2000 Other Nissan Models 4 cyl Two Wheel Drive Manual 96000 miles
Car is EFI type. Already clear the plugs, Injectors and throttle body.
When it is drive, feel less pickup at low speed (Start up etc).
After the emission test
At 750 RPM – CO value (v/v) around 9 %
At 2750 RPM – CO value (v/v) around 1.5%
When I check the end of silencer can see high amount of carbon.
When accelerator push fast at once carbon partials can see at emission.
Carbon particles can see at Plugs 2-3 km runs after plugs clean.
Feel the fuel efficency is very less. Please help to Diagnose the issue.
