Hey fellas,
Just managed to limp home with my beast which is now stuttering all through the rev range. No eml and the performance has gone down progressively over the past week or so.
She has done a few high milage trips recently after a period of 3 months when I was away for queen and blah blah, but a mate was starting her up and driving her around camp (but not if the boss is reading

)
Also did an oil change (by a garage theres a first for everything) and I did get her upto 130mph on the autobahn on sunday

- would any of these have anything to do with it?
At first I though plugs/leads or both but they were replaced about 18months ago. Cant check the leads too much as it is dark so I will check in the morning.
Now when I got out of the car I smelt something funny. Very difficult to describe but could be the old 'rotten eggs
but being burnt' smell. I'm thinking one of my cats has given up the ghost. Also when I put my hand over the exhaust it seems as if only half the engine is firing ie either 1-3 or 4-6 kaput, which follows the cat theory.
Any thoughts or am I barking up the wrong tree?
