well im @ a loss here.. i have an msd6a on my b18c set up.. i hard wired it to the stock coil and though i just got a new coil (stock) its still sputtering in the low rpms.. if i mash it it sputters. i just replaced the plugs,wires dizzy cap and new rotor. for some reason its still sputtering..

any ideas?

i had the hds hooked up too it and it read fine a week ago.. on monday i came home to pa and it started acting up again.. im about to just toss the 6a all together if i can figure out how to wire everything back to stock
