I'm getting an intermittent miss at low speed and cruising speed. It's never consistent. I've got an MSD 6A with the SS coil and I think the box may be the source of the problem. Anyone know how to trouble shoot these?
I bought a MSD box off ebay that was toast. I went to one of our local performance spedd shops and they had a MSD unit to test it. It didnt work (the tester worked..not the box). But you can send it to MSD and they will repair it. Mine is going to them in a couple of months.
Check your wires 1st, also don't allow them to touch eachother either, then check your plugs make sure there isn't a huge deposit on them.
then check the cap, check the connections at the dist for the plug to the trigger from the msd
