MSD 6AL Problems?
Still new to Cobra's, but I'm learning, thanks to this forum. I have a 2010 BDR with a Roush small block 427R complete with MSD everything. The ignition box is a 6AL.
Ever since I bought this car last December, it's hard to start, idle's really rough,
and snorts and farts when I half way get on it. I figured since the car only had 300 miles that the carb was maybe gummed up. Today, I drove the car for a hour or so and when I stop to get something to eat the dang car wouldn't start.
It would turn over, but it acted like there was no spark. I disabled the ignition box by pulling the fuses. The car fired right up and actually idled smother and ran a lot better. Is it necessary to have a box?? Is this a common problem with MSD?
