injector was OK and also swapped computer, ICM and plug & plug wire. going to get new spark plugs and double check. At idle one can see the normal flash of about 5/ sec except #3 which has a blurry rapid flash. I think that the insulator plate has again been compromised......it should be noted that #3 terminal is pretty much directly above the optispark module. what was supposed to be a simple tune-up has become a royal nightmare!.......although i can now probably do this repair with my eyes closed..
