ok
so i finally got my summit ignition box.
wired it all up 100% to the specs in the directions and now it has a huge misfire once it hits 2000 RPMS.
ive checked and double checked all the connections, grounds and everything
im clueless at this point
well
it had a very slight misfire before, but not all the time
new cap, rotor, wires, new injectors, fuel filter etc etc...
i just cant seem to find wtf is going ont
what about new plugs??? if you got platnium plugs in it and they are new I'd ditch them in favor of standard copper core resistor plug like an autolite 25
well IMO an occiliscope is the only way to find intermitent or slight misfires, if it's a large one using the koer function of the ecm perform a cylinder balance test
