So as pe my problems thread in the tech section I decided to bite the bullet and get a new MAF - first of all called HarryFairbarn off here they quoted me £260 + delivery that's too much surley!
Camde up with plan B as I'm not 100% sure the MAF is the problem I didn't want to throw that much money at it, but it needs changing anyway as there is some cheapo one on there atm. So, the plan was get one off a reasonably low mileage car that was being broken... had people quoting me well over £100 for the part all week. Obviosuly had to deal with the obligatory eBay idiots as well
Anyway all's good now got one on order paid £30 delivered from a 330 vert with 70k on that had been rear ended. I'll be happier having the genuine article on and fingers xed it will fix the rough idle - I'm pretty hopeful!
