So i recently i got a state ref on my sr20det, for illegal emission. So i decide to try to get my 240 back on the road. So i went to go buy a ka24e because my 240 is a 1989. Did the whole engine swap and and now the ka24e is in the 240 and is working, kind of. I try taking it to a smog check to see if there is any problem because when i put a cat on it the engine light turn off, so i thought i would be able to pass smog with it. Then the engine light pop up and when i show him the engine he said, there was a vacuum leak, its misfiring, and that the timing look like it was off by the way the distributor look. I had a friend do the timing and the idling according to the sign on the 240 hood.
So basically my question is that what could possible be causing the misfiring and what step would i do in order to try and find the vacuum leak? like is there a manual or a book to help me? or if i uploaded a video of my car to help you guys get a better picture, please help me its been a year since the state ref.

Also should i just bring it to the state ref or take it to a smog then a state ref?
