Message	My Spark Plugs are white and turning cherry red. So my car is running lean and I don't know why. I will know why tomorrow as im going to hook up the boost leak tester.. But yea, I was in tears earlier because I thought I blew another head gasket. But the compression check went ok. 165 in cylinders 1-5. 145 in Cylinder 6. I also did a pressure check and it held pressure, didnt drop at all. Again, the dyno a/f was innacurate... whats up with these dynos... their widebands just suck period... They say 1 thing, but the spark plugs dont lie... 2 months ago, I did the same thing, I had the car dynoed, wideband said it was running rich, then checked the plugs a day later, spark plugs said differently.
