You have the series I, non vented Opti-spark, right. If you look at the distributor and saw arching from the cap area you have either a bad cap, or its not installed correctly. Also be careful and inspect the water pump weep hole. Make sure that the distributor isn't getting coolant on it, this will kill the opti-spark and cause all sorts of problems. Also make sure everything is hooked up ie. vac. lines, MAF sensor and air tubes are sealed to the air meter body. It will run rich and bad if the ECM isn't getting a valid signal from teh MAF.
