Misfire/hesitation on 1.8T
Hi guys
I've got a slight misfire or hesitation under load, around 3k refs on the 1.8 turbo 75. I will be getting the car on the T4 very soon hoping it will tell me the issue. Any ideas here what to look for? Many thanks.

Reducing the spark plug gaps to 0.5-0.7mm is reckoned to help with this.

Ok, thanks. Sounds daft, but how do you measure the gaps?

With a feeler gauge or the thickness of your thumbnail

This gap should be 0.5 to 0.7mm
You need a set of feeler gauges or a similar gap measuring tool. And you make the gap the required size by very carefully moving the outer electrode. That's the bent bit in the first picture. The appropriate feeler blade should just slide through the gap with a slight resistance felt. TC |

On my car with those exact same symptoms it was a failing ignition coil - all carbonised up.
