I have a MY01 WRX full decat exhaust and gutted uppipe. Recently the fuel consumption has increased by approx 80-100%. The car is throwing a P0420 cel with a AF531v3 map switch rom.
Could the 420 error be causing the excessive fuel consumption? Also ambient temp are 30 deg C.
There are no boost leaks, exhaust leaks. CO at idle is 0.42 and with aircon on co at idle fluctuates between 0.38 and 1.1 over 2 seconds.
