Does anyone know what a strange puffing from the air inlet means, just got a land rover defender 90 seemed fine but now it's running unevenly, wouldn't tick over smoothly without adjusting idle up and strange to start, sounds like it slips before starting ! Have I blown something, the previous owner hardly ever drove it so it was standing parked up for months before I bought it, I have been using it daily and on motorway too.
Any thoughts or advice gratefully received
