Hi.

Need help with issues with my 931. Bought it this winter and it's a really nice low km car. It has been used very little in tha last 20 years but was serviced a year ago with belt and fluid changes. It has been running great since I bought it but last night it started having issues. When pushing hard just pass 4000 rpms the car just wont go anymore. Like it just shuts down. Can't hear any misfires or alike.
I can't see any obvious faults apart from the valve in the pic that is not attached to anything? You can see my finger lifting the valve from underneath intake/throttle body. However I have seen this before it started acting up so can't be the fault. But isnt this valve supposed to hook up to something?

Other issues is smoke on startup which when searching is something alot of 931:s seems to do and also hard to start when warm which also seems to be common.

I have no experience with these cars so help is appreciated with this issue.

Regards
Peder

Please advise.
