Is the check engine light on? Maybe you just got some bad fuel? Add some fuel additives that remove water to get you by till you can fill up again.

Asking the same questions 4 or 5 times will NOT get them answered!


Yes bad gas can cause all kinds of driveabality issues. Buy a can of Octane 104 and put in the fuel tank this should help it run better until it get low enough to put in good fuel. After that I would add some SeaFoam to the tank just help fir ther clean out the crud, you may want t replace the fuel filter after its all done.
