hi guys ! Im new to this forum :(

currently i just checked out the ecu's faults reading code by using a common method ( use a paper clip or sumthing similar then bridge them then the engine icon on the dash would be flashing...) but this is wat i got :

5 slow flash - pause - 5 quick flash - pause - 5 slow - pause - 5 quick.......and so on ( same frequency )

so i assume this is code 55 which is no errors/faults but the car doesnt feel right when i drive it : bad fuel consumption , sluggish at acceleration .....). Then i come up with an idea : unplugged the connector of AFM and then try to read the ecu again.....still the same (code 55?) :ermm: please help !! whats wrong with my ecu ? :(

Any help would be appreciated . Thank you !

Code 55 is Nissan's "Everything is OK, apparently". It's possible the AFM when unplugged just puts the car into limp mode home, I think.

The problem might be something the ECU can't detect, such as a boost leak, intercooler pipe blown off, fuel pump failing, failing oxygen sensor, dirty AFM, leaking fuel injector(s) (in no particular order)
