    bad backfire after plug replaced

    I am working on a completely stock v6 camaro just replaced fuel pump and put new wires and plugs in. It had a back fire and ran real rough when cold so changed plugs and wires and now it is even worse any ideas? The back fires sound more like a pop when just revving it.

    Maybe the timing chain jumped a tooth?

    We need mileage as well. Are the plug wires on tight? Did they click when you put them on?
