beska133 Posted January 26, 2012 Report Share Posted January 26, 2012 The last 6 months my economy has just gone down the toilet,Anyone else having this problem? Its been serviced every 5k miles, ive cleaned the throttle body, inlet manifold, icv valve, no fuel leak and runs fine, my spark plugs are black, meaning over fueling, and the car is a mk2 arosa on 36kmiles and 52 plate, Any ideas? Can the expansion tank get stuck?Does anyone have a diagram of the expansion tank?Cheers Quote Link to comment Share on other sites More sharing options...
