hello to all, i just got a msd ready to run 8354 distributor with three wire hook up. but now when i start the car i,m getting poping like is not getting full power.so i disconect the factory ignition positive cable from the firewall from the positive coil and stright wire from the battery positive to the coil positive and fire up ran fine, does it mean that the factory ignition from the firewall is weak or ? i had a stock distributor work great before.also someone said that i should get new wire and find a hot current when i turn the ignition switch on. i'm lost i thought it was drop in and fire up?
