So after the spark plug issue and suspected under fuelling I changed the fuel filter and upgraded the LPFP to one of these

So glad I bothered to clean it the Friday evening before as I love how the wheels and brakes look when spinning
. First time I've ever uploaded to YouTube and seems that it dropped the quality a bit which is annoying.
After half a dozen or so runs it seems all the big important things are running fine and fuelling is perfect now. However it sometimes holds back up top as the ECU is getting a bad reading from one of the sensors, which is on its way out, but unfortunately the ECU won't tell us which sensor is giving the bad reading so basically I need to keep driving and regularly check for fault codes until something comes up. Not great but not bad however at least now I can now go out and enjoy the car again even if its down about 20bhp.
