hi all.
ok, story of the problem, when I use to start it up, it was real lumpy, but after a min of letting it tick over or drove it under 3 k for not even a mile, it was smooth as you like and drove real nice, but if I turned it off, and started it again, it will be all lumpy and run as though its on 2 or 3, unless i left it and again it would be fine..
now, the other day, it did this as normal when I started up, and it didnt stop, I had to drive it, so did, thinking it would drive out of it, but it didnt, and then ran really bad, to the point of not revving over 1k, even with foot planted to floor, then cut out. had a play, and the week old spark plugs look shaged, so I changed them with some spares i had, it started up, but still had monster miss fire... I suspected a valve, but compression has come up with each a touch over 100, so thats not the issue, any one any ideas on what I can do to stop this, I know its not suppose to be lumpy on start up in first place, but never really caused a issue as I let all my turbo cars run for a moment before driving off, so, HELP
