    A4 2.8 plug leads

    Following on from my posting about the fuel consumption and misfire on my A4, I bought a new set of Magnecor leads. Well, anyone wanting to but a set for a V6 might want to know the fun I've had ! Ordered on line by engine code from Europerformance - really helpful. Leads arrived, and they are...

    Hve also bolted the exhaust back together. It actually sounded quite tasty with only 1 box and a side exit pipe.

    Light misfire and poor fuel consumption on 2.8 ACK engine

    It sits at 1150 for about a minute, and if you give the throttle a blip, it returns to 1150 quite slowly. Once it's warm, then it's fine. this is after the new coolant temp. sensor. Anthony

    Light misfire and poor fuel consumption on 2.8 ACK engine

    Can anyone help out with a fairly complex problem I've got with my 97 2.8. It had 3 problems, the first was on initial cold start, the engine revs flew up when I touched the accelerator, tried to take off gently, engine stalled with a strong smell of petrol. There's a light misfire at low revs...
