new motor with slight hesitation/lope

[Tuner.87]

My old motor im guessing i valve dropped so im found a new motor. It is a JDM motor so i had swap wiring harnesses and some sensors cause they were differant. I even had swap over the egr system as the jdm motor was just blocked off. But i got the motor in and it started up and at first i had a fuel leak but i got that sorted out but i still have a problem with the idle or even just trying to drive. Its got a hesitation/ a slight lope almost at idle. it seem to shake a lot when cold. I looked all over for vacuum lines not connected or something. I seen some smopke coming from motor but that seems to be disapating as i run the motor guessing its just the degreaser that was put on it when i picked it up. But theres still some coming from the back of the motor but i really dont think its it. i dont have a timing light to check timing and i changed the spark plugs any thoughts on what to check or anything. Also anyone think it would be ok to drive it for now cause 2 of our cars are down with this one so we are at 1 car? dont know if you can tell in the video but here. need to get running quick.

I would check to make sure you are getting spark for all 6 cylinders, because that's what it sounds like.
And -you are able to swap motors, but don't own a $20 timing light??

yeah i know i could go get one but wanted to find out what everyone thought first. ill try to look tomarrow for some spark

Check codes and report back.

ran that test didnt fond any codes just kept blinking quickly. But i dont see anything about spark or timing on there so is this the culprit you think?

well i checked timing it was off maybe 2 hairs but good now seemed to help a little and then i ran sea foam in oil, gas tank, and vacuum lines. definatly cleared it up and the idle sound better but trying to go its still there when i get to a constant crusing speed its fine but when i punch it it sputters and when it gets under boost i hear like a spitting sound witch makes me think it vacuum leak and its coming out under boost but im having no luck at all searching for it. i sprayed some throttle body cleaner to try and find the leak but still no signs of high idle when doing so. still gotta check spark but also wondering does a plugged cat do this. I still have the first one but the 2nd one my exhuast replaced. PLEASE HELP

Sea foam is crap!

Ok all is fixed. When i got home from work I wanted to check the spark but while i was doing that i figured why not checked the fuel inhector wires also. All looked good at first glace but then i caught i glimpse of the purpatrator. The #1 cylinder injector wire was not connected right. The clip was seated fully on the injector but the wires came out of the clip. I couldnt just get them to reseat so i got the wiring harness from the other motor and I spliced them back together with the good clip and pluged it in. Then sense it was already apart I figured i would look at the spark plugs. All plugs were fine excep for the #1 plug go figure, it was very BLAAAAACK (courtesy of MCM). So i put it all back together after cleaning the plug up and started her up and wala. She runs and is very responsive. After driving a rod knocking motor and not driving a good one all i can say is wow. much better. So now that i know for sure that the wire was the problem I just need to solder and shrink wrap the connection and she done and ready to go.
