heres a weird problem ive been trying to solve with my integra for awhile.. i dont know why its doin this but it seems to be running lean in 2 cylinders and rich in the other 2.. should i be concerned??? what do you guys think??

 

looks normal to me i wouldnt worry about it too much unless they are really different but from the pict there is hardly a difference

 

the lighting is bad but they dont look bad to me

 

To me the look oily.

 

the one on the right seems a little white...but cant tell. post betters pics
macro

 

The 2 on the right are different but I wouldn't consider the cylinders they came out of to have a problem.

Check the gaps on all 4 and see if they are off, but other than that they look fine.

Cheers,
Sean
