Really rough idle
Hi all, I finally got round to relocating the coils into the fenders and also fitted 1200 injectors (previous 600).
I was expecting the car to need a tune and not run 100% but it’s is really rough. Idle is really jumping and if I rev it splutters and hesitates.
is this normal because of the larger injectors or have I done something wrong while relocating the coils (bad leads etc)
tried to upload a video but it won’t let me

You should not have even attempted to start the car without a tune with the injectors. It is doubling the fuel, and probably flooding the cylinders and could easily cause damage. Stop, get it tuned, and go from there.

Yep, no way to drive it like that. Either grab a tuner and do it yourself, or drive to tuner with old injectors, and have it updated then. If a tuner is 100+ miles away, well worth it to invest in your own tuner and just have them email a file to load.
