Why would a 95 Neon hesitate and backfire when you hit the gas?

Answer 1

It could also be a bad oxygen sensor. Mine was doing the same thing and I had to replace the upstream sensor. If your check engine light is on go to AutoZone or somewhere and then can check it and find out if that's what it is.

AnswerCheck to see if the timing belt needs to be tighten or the spark plugs might need to be replaced. AnswerOften times caused by a bad spark plug or plug wire. To check wires try spray mist water over wires at night and see if there are sparks. If yes, you need to replace wires. As for the plugs, remove and inspect, I've seen quite a few that had cracks in the porclean. Good Luck!
