Inlet Manifold "test Port" Cover?

[MarkKJFLtd 1 1 Cars]

Hi everyone!

 

Here he comes, typical lurker not contributing until he's a question to ask....

 

Since my car has been in for a service with Peugeot (long story as to why it ended up at a main dealer), I've noticed the engine idle is higher than usual, bot hot and cold. So, decided to have a look at the weekend, and noticed the little rubber cap was missing from what I think is a diagnostic/test port on the inlet manifold? Hopefully picture attaches to show it.

 

Anyway, if I cover the hole, the idle speed reduces, and stabilises, to what sounds like its original pre-service speed.

 

Does anyone have one of these little rubber caps knocking around, or should I just try to tape it up and see how I get on?

 

Thanks in advance!

Thanks for the tip! Could well be that cap, and they just moved the port onto the plastic manifold rather than the throttle butterfly on the later cars like mine? Pic attached this time hopefully through the link...

why not take it back to where you got it serviced if they mucked it up
