Hi Benjamin, thanks for the reply

It was more a thud, like a guttural mechanical thud than a crack - plus you could feel it rather than with a backfire where it's more audible than anything you can feel

Tbh my immediate reaction was IMS due to how it felt and the loss of in-gear power

As for CELs, I currently don't have one no. I've had intermittent CELs in the last three months. I've had manifold bolts and coil packs done, but I have a feeling either the MAF needs cleaning / replacing or it's ICV, TB, inlet plenum or O2 sensor related. My Porsche specialist preferred to rule out the gas leak from the manifold bolts and the "corroded" coil packs before replacing sensors

I will ask the next garage (who do a lot of Boxster clutches) to clean out everything and maybe run the car with MAF unplugged to see if I can get rid of this idle issue

It does occasionally backfire a little actually. I have the Oettle bypass box on it and you can hear the unburnt fuel burbling - it's ace!

I think the root of this might be something to do with fact the gearshift feels "loose" when hot. The fact it's weird going into 3rd sometimes. In a way, it's really frustrating that everything seems fine. I'd almost prefer there was a problem that could be rectified and I could move on!
