Could this be the start of injector wiring issues?

Hi all.

Ive a b5.5 AVB estate.

Its now done 195255 miles.
Over the last 1000 miles ive noticed the odd miss while sitting in traffic @ idle.
A stutter on some start ups but clears quickly and today it would start 1st time after a hot run (been standing a couple of hours) as it misfired and shock the car.
It started 2nd time with a mis or two.
Left it idling and it was missing now and then and clears but drives great and doesnt lack performance.

The coolant level has stayed the same so im sure its not head gasket.......

What are your thoughs or experiences if youve had this.

Thanks
Rob
