I put 3/4 of a tank full in on on sunday on way back from party... as Niall will tell you, hard acceleration was awful... misfiring like never before, I thought it could have been plugs or coil pack failure but... tonight the car is running like a dream, real power from 3000 revs and it's like a different car altogether, there's only occasional misfires now, so maybe the ECU has adjusted itself :dunno: Don't fancy headingback to Mitchelstown for another fill up though :shock: C'mon Maxol get your ass in gear and get E5 everywhere!!!!
