p0303 misfire but only on decel
please help , i've been all over this thing and i think i may be missing something simple but i have replaced the injector and pcm because after you drive this and start to coast down hill #3 injetor pulse just falls out and will not come back until you shut the engine off and restart it and then it will just keep repeating this . any ideas ?

i replaced all injectors because i had a new set here also i replaced pcm to see if it was just shutting off the driver ckt on it's own because this vehicle runs great until the injector pulse falls out
