Strange Mis-fire - AUQ Engine
The problem is that when driving normally everything seems fine but if I use between 90-100% throttle, when I get to full load (starting at 2500rpm) I start to get a misfire. I have plugged in VAGCOM and it shows an intermittent misfire on cylinder 3. I have changed the spark-plugs and all the coil packs which didn't resolve the problem. I even swapped the coil packs around in case one was faulty, but still the cylinder 3 issue.
It's booked in a Midland VW this weekend, but just wondered if anyone had ever had a similar issue or any ideas?
Car: 2004 Seat Leon Cupra 20VT

l have cylinder 3 run hottest, so l was told. Changing the downpipe sortted me out.
