The IG mod on the side of the dist sounds bad replace that first before u go digging inside the dist for the p/u coil. Word of advice go to ur local auto parts store and by the tool to get the bolts for the IG mod normal sockets won't work save urself the headache get the tool made to do the job

It could also very well be a weak coil or a cracked dist cap or bad rotor
