Spark plugs each have their own story??

Well I pulled my plugs yesterday and noticed 4 and 2 was rich, 3 and 1 was okay I pretty sure the plugs should have the same color right?
thanks

It's a bit strange to get different readings from your plugs unless they go rich to lean from the driver's side (number one) to the passenger side (number four). I would run a compression test and see if you have excessive variance between the cylinders just to rule that out as a contributing factor. Also, I'd like for you to re-check the gap on the plugs and post pictures of them if you can.

Please drop us a line once you've run a compression test and we can continue to follow up. In addition, if you haven't already done so, I'd like you to drop in a fresh set of plugs, new wires and a new fuel filter, just to make sure that everything is on even par.

I was thinking the injectors? I will get the compression test done asap. I just removed plugs and all of them said rich. I just put these in and now the readings are different? The wires and fuel filter and new!
