Sounds like they got your plug wires on wrong. Take the car somewhere else and have it checked out. If the car is a lower-mileage, well-maintained vehicle, you can pretty much prove that it was their doing. But the first think I would do is check the firing order and make suret the spark plug wires are correct. If they changed the wires and distributor cap, you can be that they messed up the firing order. That is what caused the backfire.
