2003 1.8T - intermittent misfire on starting

Hawkesman · 5th March 2019, 19:58

It doesn't do it every time I start it, but when it does it can go on for anything from 15 seconds to a minute before it clears and then runs fine for any amount of time until I switch off.

Sounds and feels like one cylinder in particular is missing as it has a regular 'beat'. I put new plugs in, but that made no difference. I'm guessing it must be either a dodgy plug lead or one of the coil packs, but I don't want to just randomly change things out in the hope of curing it.

Any ideas people? Thanks.

PS - when I changed the plugs the plastic tops of the plug lead covers just cracked and fell apart when I pulled on them - had to pull the remaining rubber part out with a pair of pliers! Other than that an easy job.
