What can it be ?
I think I have an ignition problem. It feels like a whole lot of timing is taken out. You can drive normally at a steady RPM then all of the sudden the exhaust gets a lot louder and the RPM start to drop. I thought I had a bad ignition module, so I went and got a new GM one. Same thing... Could it be the pickup coil ? I have a new module and a new ignition coil in there. Could it be my MSD box ? Any ideas would be appreciated.

I should also mention I burn my own EPROMS and they get unplugged and plugged back in quite often. Some of pins on the white resistor network next to the actual EPROM are loose and not soldered on the netres anymore. Does that have anything to with timing ? I read somewhere that THIS is where the EST circuit resides.
