Right...

my car is missing...

I found out that a the harness to one of the injectors had snapped. so ive soldered it up and it looks fine now. Plug is back in etc and it still misses.

When I start it from cold the engine sounds perfect and then after about a minute it goes lumpy


Ive tried taking each coil pack off and it changes the sound slightly ( meaning these are ok )

what else could it be?

Anyone have vagcom near you? If it's missing it will have missfire counts logged. So you will at least know which cylinder is the problem.
