Hi guys, as you might know I've been having a number of issues with my car, in particular the almost constant presence of the exhaust system warning light.
So far I have changed the DV, N80 Solenoid Valve and the EVAP Canister. However in the past week I have been experiencing a lumpy idle and over-revving at idle. I understand this is most probably due to a faulty PCV.
My question is, is it possible that this could result in the exhaust system warning light?
