Back again with this 06 sts
tore it down and did the timing chains, new evap valve, replaced whatever vacuum lines I could.
Original issue was misfire all cylinders.
After putting all back together still same issue (mis fire all cylinders).
Checked, rechecked, triple checked all vacuum lines and intake 100% sure she's not sucking air anywhere.
Good compression all cylinders
