Hi all,

2.2 Signum Direct 2004.

Engine light on, seems to idle ok, and drive OK, its throwing up code: P112-61 Swirl Flap Stuck.

I believe there is a modification kit which is around £200 ish from Vauxhall, before I go down that route I was going to give it a clean with carb cleaner, the throttle body was carbed up recently, cleaned that which sorted an idle problem.

Whats the best method without removing the inlet manifold first?

Just remove the intake pipe, and spray carb cleaner into the intake whilst someone is reving the engine gently opening the throttle body flap??
