idle pulsing surge

Just put a D16y8 mini me swap in the ol del slow , bled the coolant got everything hooked up right "pretty sure" start the car , short idle surges , barely jumps between 700 rpms to maybe 1,000 to 1,200 rpms short surges , It does that until the engine hits temperature then you hear a POP in the intake and it idles perfect.........yeah , weird huh... checked the TPS with multi meter, works perfect , changed the AIC , changed map sensor , engine cant be out of time because it idles perfect after it hits temperature , BUT. "this may be a seperate issue" when you go to drive it down the road, taking off in any gear or in low rpms the car boogs , jerks back and forth then takes off and goes smooth past 2k , but if your doing 55mph down the hwy trying to cruise , it starts to bog. Hard acceleration has no issues , you can grab vtec and chirp into 3rd gear no issue. No idea why it warms up , makes this pop sound and idles perfect.... then bogs while you drive it in low rpms as your taking off or trying to cruise. **Update** i think the distributor has taken a fall , thats whats causing the boging.
