When I got the black car, supposedly the engine was rebuilt a few days before. I didn't really have any solid proof, but whatever. I later on found out an issue with the idle, so I took out the IACV, cleaned it all(it was pretty dirty), then I put it back in, but it was idleing at 3000 rshared_pm. I also replaced the plugs because they were pitch black. I took out the IACV again today to make sure it was right. I didn't find anything wrong, but I cleaned it again just to be sure. I just took out the spark plugs which have no more than 100miles on them, and now they're pitch black. What could be causing this? The first 2 spark plugs from the front are darker than the back 2, but they're all nasty.
