Contour Enthusiasts Group Archives Forums General Troubleshooting 250km to a tank. i'm going bankrupt..HELP!!!

I haven't read the entire thread but let me shed some light onto the situation. I was having a problem with poor gas milage lately, only getting 350-400km per tank with my SVT. I cleaned the IAT and MAF sensors, gapped my plugs to .054" (were .052"), reinstalled the stock air box and ran fuel injector cleaner with my last 2 fill ups. The result is now 500-550Km per tank with a SVT in December weather with a 60/40 city/highway split. Something major is definately wrong with your cars if you are only getting 200-250Km per tank. This is NOT normal.
