Title: any idea's
Post by: ben harcombe on 18 June 2009, 21:44

OK Ive got the first headache before m.o.t  :shocked: at last
Ive searched allover can't find an answer the car is a mk2 16v pre 90spec loom. Its now got a abf now running k-jet. Ive swapped all electric components timing is spot on been done with a gunson strobe and it still misses under load sometimes it seems to clear

And the c0 screw aint been set at 2% :undecided:

plugs and leads are normal cause of misfire but if youve swaped everything the only thing i can really suggest is to get it on a dyno
