Update... I swapped out the coils and put in Bosch plugs. That really smoothed out the general running at anything but at idle. When I'm first starting or just sitting at a stoplight it's like your AC compressor turns on and there is a shudder and I get a Cylinder 5 misfire code. Once I got a Cylinder 4 misfire code as well. It's feeling like a vacuum issue is causing a lean-out at idle. What idle related vacuum components could be playing with me? Idle Control Valve and cracked vacuum hoses come to mind. There is also a "Chuffing" sound after I turn off the car. Is this a possible indication of a failed DISA (what ever that is) valve?
