its just the #3 spark plug thats chalky black like its running rich, and your can feel it missing at lower RPM's, and up in the high revs you don't notice the miss in that cylinder. distributer is a year old and plug wires are a few months, all good pieces too, checked the contacts in the cap and it all looks good.
I am suspecting a leaky injector causing it to run rich... And at high revs i don't notice the miss so much because of the increased demand for fuel vs the missing at low revs when its getting way more fuel than it needs? I did have 1 of the 19lb injectors before the build that was sticking before i cleaned it out, so i wouldn't be surprised if that was the culprit.
is thier any way of testing this injector out while its in the car to see if its stuck open? Or will i have to take off the plenum and just swap the injector.
