Get a mapper who knows what an NPS is!

dunx

 

the mapper was andrew carr mate a think he knows wot that is one of the first things he looked at

 

What did the mapper suggest???

I agree with Dunx, I'd be looking at the NPS.

 

changed the knock sensor today and put fibre washer below it its improved alot but still doesnt feel right we spoke about nps while it was being mappped and the laptop showed it to b working fine dont really know wer to go from here is it easy to accsess nps as theres a another 6 speed box ther that i could swap nps over
