Backfire problems on my 1994 Mustang 5.0
This is what I did. I put 24lbs injectors in it. And this is the work I done to try to fix it. I put new plugs, new 9mm wires, new coil, new MSD cap and rotor, 2 new O2 sensors, put fuel injector cleaner, put the timing down to 12*. And it STILL backfires on normal driving.

I would clean the MAF and double check that it is calibrated correctly, then you might want to make sure your dizzy is stabbed correctly and the timing is correct. If that doesn't fix it, you may have a blown head gasket..
