Hi hoping some one can help me with a fault on my 2007 ed 30, noticed a slight miss on tick over when I stop at junctions and lights, and a hissing sound on engine switch off,
Closer investigation I could see the pcv was sucking in air from a small factory hole on the saucer part, took it off and seams to work fine you can suck one way but not the other, ordered a new one and fitted it just to be on the safe side,
With the new one fitted the engine revs and hunts between 1000rpm and 1500rpm, it pulses continually, I have changed all the spark plugs and new air filter and cam follower and dv, notice if I open the oil filler cap slightly to cause a vacuum leak it ticks over normally, hope some one can help it is driving me crazy,
