Does anyone have any ideas as far a sensors or any problems that my have arose. as far as maintence, the car was gone over bumper to bumper around 2500 miles ago...plugs, wires, coil packs, ALL fluids, thermos, hoses, battery...you name it i did it. Thank you for your time

First thing I would check is go over your plugs and wires. If you just did them, maybe you didn't tighten up a plug tight enough. Or maybe a wire rested on a manifold and burnt through. Maybe one wasn't on tight. So that would be the first thing I would check.
