Need advise on very bad FC (cl7a)

[dfx]

Leak exhaust will cause bad fc since o2 (oxygen) sensor pick up wrong info and send wrong signal causing car to run rich

Good that u managed to sort it out

Clean up the throttle body - checked already, still good no cleaning required
Clean up the MAF sensor - not done
Calibrate Idle Control Value - not done
Change filter - Using stainless steel filter, cleaned
Change spark plug - Changed to IK20L
Change ignition coil - not done
Check tyre - consistently done
Reset ECU - done


I might have found out the cause of the issue actually. I went to check my exhaust which one kind bro mentioned and the mechanic at GT Garage told me that one of the screws was loose and there was a leakage. Got it fixed up and today is my first whole day out on the roads and there is a MASSIVE difference.

I am already clocked 220, 3 bars before halfway line. I used to clock only 150 on the halfway line. Can u imagine !!

Thanks bros, will continue to monitor. Hopefully this is the end of my nightmare.[/quote]
