Honestly, your lack of grammar sucks. A problem can only be solved by either pure luck or by completely understanding the problem. With that said, I don't entirely understand your problem. With this limited explanation of your problem, there could be a multitude of culprits. Have you applied any problem solving skills to try and isolate the issue, or at least narrow it down. Your problem could be a simple to change, cheap to buy fuel filter, or it could be an expense PMD.

Please explain your problem better.
