I hope this is not what I think it is ... 700 1992

Have had a rough idle on the 745t - finally got about to cleaning the throttle body. Still rough. Pulled each plug wire one by one - and found that the back plug seemimgly not firing at idle - although I can hear the 'pop, pop' of the spark when I hold the wire just off the plug. I pull it completely away and it makes no difference.

Go get a set of new plugs - Bosch plats - pit them in - same thing. It does seem to be better - but still rough.

What do I have - bad wires - or ..... a bad valve? (arrgh - hate to even think it)

By the way - it runs fine at speed - but it has seemed to have lost some of it's pep. Also the NGK plugs that I pulled are burning clean - all look the same.
