It could be the coil itself. coming from personal experience, i've personally seen two accel superstock coil's go bad within two weeks of installing them on vehicles. one, was on my truck, which lasted all of six days, and another, on a customer truck at the dealership. hi's lasted for two weeks after putting it on his truck. i tried to get my money back from both accel and the local checker, but checker laughed me out of the store and accel ignored me until i gave up ten months later. i'd personally put the stock coil back on.
