1998 T5 misfire at high revs??

[Nutternick]

I have just got a 1998 v70 t5 auto and it develops a misfire when accelerating hard higher up the rev range there is no misfire low down.

I have just ordered new plugs, dizzy cap and rotor arm, is there anything else i should be looking out for?

I dont want to replace the HT leads until i have ruled out the cheaper stuff

Could be a crank sensor bud

If you have ordered genuine Volvo plugs it will solve it.....if you haven`t then it won`t.......99%
