my stage 3 (t34 greens ahmed chip) saff 4x4 has been holding back when it comes on boost lately and was told that the plugs need changing,so got some 071's from ford and gaped them at 0.65 as everyone suggests and now its idling funny between 800-1200 rpm and sounds as if its going to cut out,took all the multiplug connections out and give them a good clean and its still doing it and when i take it out and give it some it really holding back when it comes on boost,i remember reading that there were some faulty 071's in circa and that changing the plugs could make it run lumpy.

any suggestions on what to do next as its got me baffled??

thanks, Rick
