I'm having problems with my '94 excel. Up to now its been a great car. Lately (when it gets warm)it 'shudders' or jerks from a stopping position when I press the gas, sometimes. (It not consistant except that it happens when it has warmed up.) I've tried new gas and changed the oil filter and still it feels like it just isn't getting the gas to it. It wants to go but doesn't have the fuel to do it. Has anyone come across this problem? I'm not sure what it could be? Thanks for your help...<img src=icon_smile_question.gif border=0 align=middle>
