Hey all. I am having some problems with my 93 sc. I cant seem to get the car to run in boost for long. before it would only run in vac and would even die often just idling. swapped out the fuel pump relay and took off the screamin demon coil which had a a dark brown burn inside one of the plug wire holes and the actual wire itself was burnt too. took it out for a run with the stock coil and it ran fine until high rpm boost. It just cuts out and wouldn't start again. I have a second coil that I am putting on right now but What other problems could cause the car to miss and cutout. I've been looking into everything
