Having a problem with my 2001 s type. Car has to sit and build up power before driving. Passenger side fuel pump changed, fuel filter changed, now this problem. Has anyone had this issue? Oh yeah, no check engine light?

Thank You for Responding!

Check sensors via OBD, so cheap it's nearly free. Check fuel trims, same comment.

May be cats, but they're costly so check them. IR gun, borescope, whatever works fpr you
