Popping sound....questions???

[tbi92rs]

OK, just got the car running again, Here's whats been going on.

got the car fired up and had a loud "clunking" sound. Turns out I forgot to torque my #8 rockers down. Oops. Fixed that and ran fine in the garage. Set timing at 12*, 40psi, and went in for the night.

Came ohme today from work and took it for a drive to the local cruise-in. It felt liek it was running crappy and was cutting out/stuttering all through the RPM's. runningl iek total crap.

got to the cruise in and got the FP down to 38 and drove it as so to a outing with friend about 10 miles or so out. More I drove, crappeir it got basically. got it home and checked itming...it was under 0, about -2 or so. Took it back to 12*, ran a lil better but it didnt get rid of this popping/backfiring and STILL runs crappy. It feels SLOW. Same setup as before. Found a burnt 8.8 ACCEL wire, and replaced it with a spare 8mm ACCEL wire. still runs crappy. Im using my 200 mile Autolite 103's gapped at .035 BTW.

What do you guys think. I want her running good so I can enjoy it. Thoguht it was bad gas but ran it down to nothing and put fresh 93 octane in, sitll runs crappy. ANY IDEAS???

thanks.

Is it possible that you over torqued the rocker causing the valve to stay open? Does it feel like your down on a cylinder? Did you set base timing with the spout connector pulled?

I had popping issues a month ago.....bad ignition module...

spark plugs from factory specs are .052 you should be
.045-.052 unless aupercharger and spray for that small gap.

I had my gap at .040 then replaced module and gapped to .050....runs fine....on speed density car
