I would try the ignition amp. the original one is hard to find and will cost you well over $400.00 under the Jaguar part muber as the amp is part of a module and not soled separeltly. On the front of the intake manifold you will see a black box mounted on it with wiers going to the distributor and ignition coil. remove the box and open it. the amp is black and attached with two screws with 3 or 4 electrical spade connectors. That is the amp and should have a GM part number on it. Take that to a good parts store. It shoud run you around $30.00 bucks
