Way to go on the jumper test! This is a great feature of the 95s! What code did you get? A 332 is pretty common if you have clogged up EGR ports. These ports built into the upper intake run from the EGR valve to the main air intake just behind the Throttle Body. You can clean these with throttle body cleaner and a soft rag once you remove all the intake stuff and the TB. Also check for cracks in the green plastic vacuum hoses leading to the EGR valve and other components.
