Hello can anyone help????.....I’ve got a 2.0tsi 2009 ....i can start the car up no problem but once the revs drop the engine idle is really bad 
also when you drive it sometimes it misfires so.....i thought it was the coil packs so i had them replaced with spark plugs and it still does it .....but when i disconnect the Pcv valve pipe from the inlet manifold it ticks over lovely so I’ve had the Pcv valve with pipes replaced..........but i still have the same problem???? 
someone else must have come across this problem???? I just dont understand what it can be??? HELP HELP PLEASE
