I give up! I got no other leads to go on. pulled the spider again and the injector was clean as a whistle after the seafoam treatment. she has spark, great compression, fuel pressure is steady, valve train looks good. Still a misfire on #3 per the code but she idles and drives fine now. reflash the computer???
