I am having a crap time trying to diagnose what is going on with my car. Just over the past 2 weeks or so, after driving around for awhile (about an hour in town), the car starts acting funny. When you press the accelorator it seams as if the motor stops getting gas for about 2 to 5 seconds (engine stops reving and car slows down) then it will engage for lack of a better word and it feels like you are being thrown forward. It will repeat this several times until you maintain a speed. If you go up a hill the same thing will happen. It usually happens when I get low on gas, around 1/8 to 1/4 of a tank. You might say the fuel gage is broken, but I've had it lower than that before to the point the fuel light stayed lit and ran for another 20 miles. I was thinking it might be the fuel filter, so I replaced it last week. Then while out driving around this weekend I had the same herky jerky thing happen again. Also, there is no noise aside from the engine rev, and no interior warning lights come on. So that means it's fuel or fire. I can't afford the $80 to have a diagnostic's done then turn around and spend another $300, or whatever it waill cost, to fix it. Someone told me it might be the fuel pump, but if it is the fuel pump won't it just quit. Oh!!!!! one more thing, if I stop and turn the car off for about 10 mins, it seems fine. If anyone has any Ideas that might save me some money and a lot of headache would be greatly appreciated.
