Recently I've been getting a lot less miles to the gallon and it's not been as keen at lower revs.
Time to investigate it I thought, so hooked up the T4 and had a firstly had a look at the maf with the Mafam switched
off.
Guess what........ bang on spec throughout the rev range.
Now with today's findings and those recently on Jon's car I think it's maybe a good idea to have the maf checked out properly and the Synergy set up to suit if the maf has indeed deteriorated.
Guessing that it's out of spec is either going to waste money on fuel by having too much mafam, or indeed by replacing the maf thinking that it's out of spec.
Let's face it they all are aren't they............not necessarily
