I recently followed one of the helpful guides on how to clean the inlet control valve on my stilo 1.9 jtd. Previously the car had started running like a pig eventually barely managing to get up a hill. When I took the valve off it was almost completely blocked up! cleaned it all out and also got out as much as i could from the other side (casing that extends over the top of the engine). Initially the car improved immediately, no more smoke out the back either. Over time though it has started to run a bit rough again also with some smoke when i put my foot down.
any ideas on what might be happening? I've thought about putting some diesel engine cleaner through the system to see if that helps but wondered if others had advice?
Thanks
Nick
