    Hey I have a 2000 1.8t sprort which was chipped when I bought it. Had it in for mot last week and the 'CO reading was up at about 10.2 . My mate at the garage read live data with Snap-on solus and found the fuel trim levels 2 be mental. 99.2%. There were no stored codes. Any ideas of where 2are start with this as im pretty sure this will be the reason im only seeing 20 mpg. Thanks
