need help 97 blazer back firing repeatedly please respond
 

I have a 97 blazer i had replaced starter, plugs and wire, distributor and rotor, belt , pcv valve and elbow, & fluids. when I started it, it began backfiring repeatedly any ideas

check your firing order. if you replaced the distributor, you should also check the timing. sounds like something is either out of order, or in the wrong position.
good luck.
