my less than pristine 98 with only 120 000 miles on has developed a massive dead spot and misfire between 7k and 8k, once through this it's better but not perfect. Most of the use she gets is up to 7k but it's irritating all the same when I do want the extra revs. Carbs are worn to fook of course although it feels electrical. The TPS doesn't affect higher revs does it?
I have some spare coils so may fit them and check connections of course but I have heard many other stories of this dead spot, almost like turning the ignition off, but no resolution other than substitution hoping to hit the cause. The plugs aren't that old but if they were knackered it wouldn't pull through. The problem is worse due to the open 2 port blue flame of course but it never used to be there
any definitive ideas other than the usual clean carbs, change plugs please
