What Jet's talking about can happen under load with cars running a higher boost level. Your issue is at idle so the gap won't be a problem. 2 Link to comment Share on other sites More sharing options...

Then refuse to replace them because they are 'new'Food for thought. Link to comment Share on other sites More sharing options...

Plugs I do firm but not too tight. The bad idle was there on the last set of plugs too so doubt it is that. Link to comment Share on other sites More sharing options...

That often gets overlooked for slight air leaks.I've had a car before we're the brakes still felt okay but the booster had an air leak causing sh*t idle.

Found a dodgy rubber joiner on the turbo inlet and replaced that with a blue silicone joiner. Tightened the upper inlet manifold bolts I could get to. Exhaust manifold bolts are OK. Tightened the turbo nuts. Tightened the spark plus 2 were on the soft side. Checked all hoses. Idles quite a bit better now. Not perfect but better.
