Just installed this jspec(temporary for a few months till i get some more funds to rebuild it myself).

It seems to be missing alot, some ppl say it's ported but i don't think it's missing enough to be, plus it's idling at 800(barely).

I'm running no bac, full tb mod etc. Video of it is once it's been warmed up. I haven't set the tps could it be a factor? Also i have a couple exhaust leaks(misplaced my good gaskets for my dp and midpipe so using the jspec dp gasket )

Things I think could be causing it to miss:
-Old Plugs(waiting for new ones, no local mazda dealer here)
-Old Gas(6 months old)
-Rotary Gods are mad at me for installing a non rebuilt jspec
-O2 sensor isn't wired up(on the todo list, but i didn't think it made a difference at idle)

Anyways here's the video:

Any suggestions/comments appreciated.

 

its most likely, in my opinion the plugs/wires...maybe..

 

not o2, probably plugs and wires like black said. My o2 isn't setup either and it runs fine just kinda rich.

 

Alright, that's a relief. Will swap in some other old good ones to test this theory.
