Hello,
I have the above motor and it seems to have a miss in the 3500-4000 rpm range. Kinda feels like it looses power for a moment. I have replaced all fuel lines, fuel filter, rebuilt the pulse pump and the injectors have been cleaned and calibrated by Brucato. I haven't changed the plugs yet but that is one of the things that I'm considering next. Also I don't have the anti-siphon valve in the fuel line. I'm also wondering should I replace that?
Thanks
Tony
