    Does it do it at idle or only when driving?

        Sounds like your timing isn't advancing properly... what distributor/coil are you running?

              Check for timing advance. Make sure its 10 degress BTDC with the SPOUT unplugged. As soon as you plug it in at idle it'll jump 10 degrees or more. Without that connected you'll have zero advance which will seriously affect power and might cause that popping. Its pretty common for people to set the timing to either 10 ATDC or set it with the SPOUT plugged in, which really screws the whole thing up.

                      Maybe my timing is off?.. hmm.

                      Will the computer spit out a code for that?

                          No. Timing being off is a mechanical problem, not an electrical problem. Say you have a burnt valve, that's not going to trip the CEL. If you have a bunk TPS, that will trip a CEL.
