Ste

I personally would look at maf had same symptoms with my classic and p1 it was the maf for p1 and maf and loom for classic (I cut back as far as I could on the loom about 500 mm as it hangs over what I would call it's hot side ) what is it your driving

What you need is a machanical speed converter that fits in between your speedo cable ..this also lifts the restrictior which is fun for a bit until engine goes boom
