B5 1.8T misfire issue

[Pat D]

I can't remember the last time I experienced ignition missfire but it seems to be doing so under WOT from 4 to 5k revs and almost feels like a full mis on all cylinders as it jolts the car a fair bit.

I haven't checked the plugs or coils yet, but was wondering if anything could cause a miss on all cylinders at the same time?

unpluge airmass plug and try it if it gonne , then your airmass bye bye

Coil pack probably they are famous for eating them, audi have a goodwill programme they replaced all 4 in one of our cars last year

Pulled the plugs out and noticed the gaps were quite large. Re-gapped them and were back in business

Couldn't find my feeler gauges, so box cutter blade at .65mm worked a treat
