I have an 01 caravan. At first she didn't start. Replaced plugs wires and fuel filter tps and crankshaft sensor finally got started with help of starter fluid. Now has rough idle she sputters on take off. But after that she drives smooth. She feels like she wants to turn off at stop but doesn't. Does anyone have ideas. Please email me. I don't want to take it to dealership if it's something simple. N.rivera@hotmail.com
