anyways, after a recnt swap it started right up but had small missfires and a small backfire and deccell i didnt bother to make sure all cylinders were firing. i went slowly added some grounds, replaced some grounds, checked ignition tming, changed plugs and wires, checked injectors, checked compression. started it back up nothing has really changed 1 and 2 fire fine. number 3 has spark and PLENTY of fuel but doesnt fire when its all hooked up, number 4 also has spark and fuel but is only firing every once in a while (i can hear it kick in, and the new plug is BLACK. #3's plug is still brand new only wet with fuel. what are my options here, is the # 3 and 4 cyl injectors leaking? distributor or coil possibly?
