Today my 08 Cupra has become very lumpy at idle it might be misfiring.
The revs will go up to 2000 then slowely come back down to 750 run really lumpy then back to 2000 and over again.
Any ideas?
Possibly. I tried to take the inlet manifold off to clean the idle control valve but caused more damage. I think you've seen the other thread!
Tomorrow there's a real man coming to fix it.
Thanks anyway.
