i have a 92 gmc with 350. i have the msd 6a and the msd coil. ive had the setup for about 8 months and recently under heavy acceleration it just bogs down and misses. ive checked my fuel system and seem to have good flow out of my injectors. what could the problem be?

That sounds like it could be something in the secondary ignition. This includes the coil, wires, cap and rotor. Check the cap and rotor for any defects or cracks. Make sure that the spark plug wires do not have too much resistance. Check all of your connections, especially the ones at the battery. A bad or corroded crimp can cause some problems with the MSD, especially under a heavy load.
