H22a SWAP ACTin all Funny!

Ok.. Halla at ya boY.. preludERSssss. im new to the H-DUC!
Let me first start off by saying i just got my car back from a 9 MONTH SWAP.... yea i know.. lond Ass time!
I put a automatic H22a into my auto. 98 HOnda Accord.
But now i dont know what the hell is the problem..

1st.. While just chillin at a light, idled the damn car feels like its bout to shake apart..
(WHY DOES THE ENGINE SHAKE SO MUCH? is THRR ANYTHG I CAN DO?)

2nd.. the fuckers who did the swap wanted to be lazy or something.. and not use the Prelude Tranny that it came with.. so they used my 98 accord Tranny saying it works with the ECU, bad thing is.. that tranny slipped alot..
(CAN I USE THE PRELUDE TRANNY ON A OBD2 CAr? OR SHOULD I STICK WITH THE ACCORD TRANNY?)

3rd.. Some of my friends were saying that id get alot more out of the engine if i switched over to a OBD1 ECU.. im like ok.. lets do the damn thang.. but how?...
(WHERE CAN I FIND A HARNESS FOR A AUTOMATICE 0BD2-OBD1 SWITCH?)

well other than that i need to buy some new O2 sensors and Radiator Fan.. AND new Tokicos.. (SHIT IM GOIN BROKE MESSIN WITH THIS DAMN THANG!)

1) Bad engine mount / loose bolt

2) There is a difference between automatic and manual ECU's, but I am unclear whether using an automatic Accord ECU on an automatic Prelude tranny would work. Presumably it would.

3) You can buy one on eBay, among other places.

yea dawg
