Hi,

So I have an efi turbo on 701 injectors and 195 chip.

It's missing and juddering mainly around 2k revs.

Tried, leads and plugs. Ecu, map, Co pot.

All the same issue.

I need to get it set up as it's my project but I don't think a set up of fuel pressure and Co pot would change the misfire.

It's mainly around 2k and isn't as bad if you hold 3k and so on. If doesn't misfire if you put your foot down.

Any idea? Would a coil pack cause this issue? Or would that be all the time and the same?
