Ruff idle since pcv change ?

[edition30ldn]

Hello everyone,

so recently I had the forge PCV and catch can fitted and had alot of white smoke so decided to change straight back to OEM.

but Now when i do a cold start the whole engine idles ruff. then After 30 seconds or so it returns idleing to normal. and recently got a  P2187 error lean on idle. did not have any of these problems untill i took off the OEM PCV now the car has never been the same , anyone help??

sounds like a vacuum leak. check all connections are clean and fitted nice and snug. maybe consider replacing the gasket on the PCV housing too.

sorry mate, just seen your original post on this.. you have already replaced the Seal :)

double check all connections. Also there's a thing about the Rear PCV and front PCV part numbers that suit each other. so have a read into that and make sure you don't have a mix match as that will cause it. (if you have the Rev R on front, then I believe you need to make sure your rear doesn't have the check valve) something like that anyway, from this info you can research and find the correct answer.
