white 02's, normal color? Looked at my 02's the other day and there all white. The reason for checking them is the cars poor mpg, gets sluggish after warmup. I cleaned them with some electrical parts cleaner. Didn't do anything for cleaning them. Might try the propane torch though. Are my 02's fine being white? Thanks.

Plug color when I changed them a few months ago was fine , light grey On the dyno the A/F was 12 at peak hp and was reading 14.7 at part throttle like it should. The dyno was just a couple months ago. I will check the newer plugs today.

One weird thing is I had to take my car into the dealer today so I put the stock tune back in along with stock lid, took maft off and then watched my gas gauge dropped very fast. I went on a long trip and my gas gauge only dropped 1/2 in 229 miles but after I put the car back to stock the gauge dropped almost 1/2 in 60 miles. I used contact cleaner on the 02's the day before the trip and got great mileage. I am stll thinking ther 02's are wacky.
