Hi dr,----- I see you are between a rock & a hard spot,being away from home & having problems. Your 97 has the 104 straight six,secondary plug wiring is under the inserted panel in the center of the valve cover, six 5mm hex bolts have to be removed to remove the cover.Also remove the air intake tube between the air cleaner & intake connection. Do a search on "plugs 104 engine",plenty of info. The reason you have the dead miss at idle is because the ECM is seeing misfires & shuts the injector down for that cylinder to protect the CAT-coverter from unburned fuel from that cyl. I suspect you have a bad resistor connector under one of the 3 coils,I would replace all 3 while you are in there, also the plugs if they have been in the more than 40k miles.The only place you are going to get the connector real quick is at the dealer, only install Bosch Super NON-resistor #F8DC4 plugs, NO other, this plug is designed for your engine secondary spark system. Just pull straight up on the coils after you removed the primary connectors on the side of the coils. Good Luck ,------ Ray
