still having fuel issue

last weeks fix. respliced injector harness splice, worked fine. found clogged injector, cleaned, worked better. found clogged fuel rail port, cleaned, now it runs perfect. but at idle. when cold it sounds like a big block with a major cam. cannot drive it until warm, about 15mins. if i try to accelerate when its cold, it spits a stutters. ONLY WHEN ENGINE IS COLD DOES IT DO THIS! thinking it might be cold start injector? should it have 12volts when key is on, like other injectors do, also runs extremely rich, if this has anything to do with it. let me reinfosize, that once engine is warm this 22re runs great exept for running rich. any ideas on what to start checking, im going tommorrow , to get parts off a blown motor, like, tps, maf,distrib, etc...
