So I decided to change the plugs and wires myself this time, after reading about it here. The plugs where last changed about 30000 miles ago at the ford dealer, probably 4 years ago. oops its 95 sc 5 speed. So I found #5 and#6 spark plugs where about 1 full turn out of the cylinder head. would this cause any problems? performance wise. Cause I have a intermittent stumble at cruseing speed 1500 to 2000 rpm. thanks all.

Well, it could be letting compression out which would make less power, which could cause a stumble.

I would wonder about an intermittent ground with the plug being loose. and not having a good hot constant spark, but prolly not. you would hear a commprssion leak i would think. and it would erode the aluminum around the plug. most likely the stutter is from the plugs needing regapped-changed.
