My Car Hesitates When Starts; Stops; Happens Again When On An Incline. At Times This Hesitation Doesn't Happen At All. About 1 Mth. Ago I Had Part Of Fuel Line Replaced. What's The Matter?
When car starts, sounds like a tank - at start of driving car hesitates and then runs normal - that is until I reach an incline and it hesitates and can't go much over 30mph. There are times when car runs fine. Had part of fuel line replaced 1 mth ago - could this have something to do with it? Filter? HELP
