Re: Peugeot 307 Random misfire
Martin Stackemann
Tried flushing and changing oil and filter no different.The more I'm getting into this the more I think it's an E C U problem it's like clock work the minute I rev it between 2500 and 3000 within 5 seconds it pings and anti pollution light comes on and it misfires switch it off and all ok someone has said it seems like a mapping problem which can only be done by a Peugeot Dealer on there Planet system anyone know anything about that?
