Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

chaps car has been sat around for a few days and sadly expsoed to the elements jumped in her this morning and very lumpy on tick over and when low rpm in a high gear. clears the throat when over about 1500 rpm so don't think it is serious or like plugs or leads. after a run down the motorway for about 20 mins then it seems to be better. could it be that as it has rained so much the water has gone direct into the air fitler box as there is an expsoed hole at the air vent? and soaked right through? would appreciate any comments or if this has been seen before on a NA C2 3.4 thanks Nick

Won't be water in the air filter box. The intake 'hole' leads down under the air filter and there is a drain hole there to let the water out. Air is drawn upwards throught the air filter into the engine. Ian W
