So i pulled my new plugs after having them in for about 50miles and for some reason why cylinder 1 is lean, cylinder 2 is rich, cylinder 3 is lean and cylinder 4 is rich.

Why would my car be doing this i have good compression so im not sure what to look for i switched the coils around and same thing happen.

Could it be bad injectors? I have the injectors wired to my ms like this inj1 fires 1&3 and inj2 fire 2&4.

Remember now this is on an SR20DET red top S13.

MS2 with edis4

 

Anyone????

 

any logs?
checked with a pyrometer the diffences between cylinders at idle?

 

I no have meter =[ ill try and log it tomorrow for you.

 

Im starting to think i have bad injectors, i put new plugs in and took the car for a light 10mile drive now i get cylinder one very little black, cylinder two is almost all black, cylinder three is the same as cylinder one and cylinder four is not even close to what they were like last time. This time cylinder four looks normal, just a tad bit richer then 1&3 but not as rich as 2.
