Has anyone had a bad tank of V-Power before, if so did it make your scoob run rough, hesitate, back off an loose a bit power, it was more down in the rev range, i thought it was my MAF going AGAIN!! but i disconected the MAF when it was running an it stalled straight away, its seemed to of got better again after another fill up but not fully back to normal, how long did it take yours to clear up?? if its not that then what else do you reckon it could be, the lamda sensor it not that old either

 

be a bit carefull, if the fuel is contaminated then it could do damage.

best bet, get it to a specialist and have them drain the tank and then replace fuel filter and then refill it with good fuel, better safe than sorry.

but also prob worth getting them to give it the once over first to see if its something else rather than contaminated fuel, also if it is that save some get it tested and seek compensation

 

I had a bad batch of Optimax once. Only driven for a day before it blew my engine!!
Car was mapped for 98 ron btw
