I have a 95' V6 contour. It has been running bad only when it is cold. I push the gas to the floor and it just pops and backfires. Then once it starts to warm up(4 or 5 blocks down the road) it runs perfect. It seems to idle fine when cold just once I start to give it gas to move it starts to backfire. I changed the plugs and wires as someone told me to do. This has not solved the problem. Any other suggestions? I don't feel like replacing every sensor and part to find that it was not the problem. Any ideas?
