Ive just completed my Rb25det neo swap into my r32. Its having a miss on idle, I get RB's dont idle great anyway but i just wanted to get an idea on what might be causing it.

Below vid sounds a bit like my car (but isnt my car)

My engine is fully stock, just front mount and a walbro fuel pump. I have a cheap FPR I'll chuck in to make sure its not getting too much fuel.

I have only done one pull since the swap and it felt ok, I just wanted to make sure it was safe before I take it for a proper drive.

Could be the coil pack.

I have seen many many threads of people going down the rabbit hole with RB misfires. Playing the game of buying all the things until one fixes it :), it seems for them though the car barely idles at all..

My guesses are:

- Bad coilpacks/sparkplugs

- Vaccum leak

- Dirty fuel injectors

- Engine issues
