I talked to the shop that did all the work on my car today about my accel 300 plus ignition box...Thay sent it out to have it tested to see what was up with it,they said they heard back from acel and they said it was OK but they suggested changing my coil.I dont understand this i have been driving my car now for a couple weeks on the stock ignition it seems ok but on the dyno it was choppy due to the spark being blown out.Now my ? is how does Accel know that my coil is bad and i thought coil work or dont work..so now im confused HELP..
