Hello
New proud owner of 1998 boxster

Well I have these codes come up and I went to good local mechanic (not dealer because they are 4 hours away) and he looked for vacuum leaks, cleaned maf.
aos was changed 3 months ago.
He spent 2 hours and basicly said he is not sure what to look for next.

Any suggestions would be greatly appreciated.

Thanks
