Like I mentioned in my post or maybe I wasn't clear in my description I inherited this issue from the previous owner. Since I purchased it and because I have no clue about the previous maintenance I one at a time replaced each set of items to no avail. I did the obvious stuff . I first replaced the plugs, then the wires and the coil packs (twice on the packs because I purchased a used set of OEM coils the first time). The car idles fine and runs down the road good. The problem mainly happens when I stand on it. With the car running I removed each wire  one at a time and there was a noticable difference in the idle each time so I'm fairly confident that each plug is firing( at least at idle speed).</p></blockquote><p></p>
