Rough idle

Post by jasst »

Took the car out today, (2.0 fsi) and the idle was as rough as hell, really hunting, under power seemed like normal, and drives ok, Good old Google suggests it may be the PCV valve ? did what was suggested and put finger over small hole on valve, and could feel suction which apparently I should not be able to? Plugged code reader in and no codes stored, and disconnected MAF, which made no difference, so if it is the pcv is it better to replace, or fit one of the kits that delete it
Edit:- now down on power all through the range, too many codes on vcds to list, will see what difference a new PCV makes.
