I currently just got my swap started up, and cylinders 2 and 4 are misfiring. It acts like it is 180 degrees off or something, it is still the original imported distributor, cap and rotor and spark plug wires, fuel injectors. however i did change the plugs. I pulled the new plugs out after it was started and cylinder 1 and 3 were clean, but 2 and 4 plugs were black.

anyone have any suggestions of where to start?

 

Ignition timing is 1342.

 

bump

 

cahnge cap and possibly the rotor. when i first got mine the cap was cracked and caused mis firing.

 

all i can say is to just replace everything. cap, rotor, wires, clean ur injectors, thats prolly ur best bet.

 

I bet some money that your 3 degrees off timing that's one tooth.

 

timing checks out good and everything else is good, do you think the injectors are not firing at the right time or do u think they may be stuck open, because there is spark and when i pull the plug it is all black from what it looks like carbon, is it possible the injectors could be staying open and are messed up?
