So the car was parked up for about a month. Started it up and its burbling like a scooby. Drove it up the road and goes like it has only 5 hp. Spark plugs are new. Suspected it had some sort of air leak before cos was idling at 1200 and would intermittently and very faintly come off power for a brief second whilst crusing but now is a lot worse. What could it be?
