I pulled my plugs cause I read you should check ur plugs after a hard run to see if your running lean or normal or rich

I pulled them and the Top 2 are Tan/brownish with tiny black spots
bottom 2 are real Tan/ with more ruffness then the tops

 

eh???

 

The problem with reading plugs is that if you're lean at WOT the plug will be white, but when you slow down and then idle into the driveway you might be running rich which will darken the plug and make for an inaccurate reading. If you want to check your WOT mixture use a set of fresh plugs. Go run the thing hard through 3rd gear and then hit the switch to kill it. Coast to stop and check the plugs. I don't really recommend the above because 1) it's hard on the turbo (assuming it's a TII) and 2) if you turn the key to off and lock the steering at high speed....any speed....you're screwed!

Ideally you're looking for a nice tan color. Not white.
