Hi all, newbie to the forum.
I did tag this on the end of another post but realised it's probably better to start a new thread.
Anyway, I'm hoping if someone can help?
My 2014 991.1 GT3 which has had the engine replaced under warranty (in 2014) has a misfire between 1500-1800 rpm under load. The misfire can be driven around using the paddles but in auto the box drops it right into that range and it's very jerky and annoying. It only does this when the engine is warmed up.
Most of the scary issues I've read seem to be about misfires at the top end of the rev range. I've had the plugs and coils replaced, no real change. There are no fault codes either.
Any ideas?
Happy for somebody to point me to another post that covers it if there is one.
Many thanks in advance.
