1st problem: Is the new engine the same specs as the old one? If not your TBI computer could be throwing a fit. Is the SES light on? And have you ever cleaned the injectors (pull the air cleaner and with the engine running at idle look at the steam of fuel from the injectors, it should be a a nice cone)
2nd problem: How old is your battery? How big is your alternator? How many watts is your amp? Sounds to me like there isn't enough power to go around, and it could be part of the cause of the 1st prob.
BTW...
