    Jaguar s type - idle problem - racing & stalling (FIXED)

    my 2000 3.0L Jag s type has developed a problem over the last week...

    it runs fine when cold but when hot (30 min journey) it races to between 1500-3000 rpm when slowing down at junctions but drops to tick over when at a stand still but after 2 or 3 mins it will stall ...

    it accelerates fine and pulls as it should.

    i cannot see any (or hear) air leaks in the inlet pipes - any ideas? air flow meter ? split engine breather pipe at the back of the engine, under the manifold?

    thanks
    mike

    So the rubber elbow is for the vacuum? (rear on inlet manifold next to bulkhead) - it seems to idle correctly if it pull the pipe off and hold my finger over the pipe...

    can i replace the elbow without removing the inlet manifold..?

    thanks

    repair done today.

    time taken about 4hrs all in with messing about.

    problems - vacuum pipes brittle and fuel pipe starting to crack and perish - will need replacing in the summer...

    ive made a quick PDF on what i did.
