Air leak, was the plenum off?

Brake servo pipe ok and connected, no O rings missing or displaced between the plenum and inlet?

plenum was off to do the cam seals. O rings seem ok.

John has just been on the phone, asked him to do a paperclip test.
Sounds like he has the following codes..

13, 16, 17, 19

Knock sensor wire trapped wouldn`t cause uneven idle. What about the carb spray trick to definately rule out vac leaks :-/
