It appears my driver side EGT (exhaust gas temperature) sensor has gone bad. The passenger side is record the temperature normally and changes as the car warms up and cools down. The driver side get to a set tempature and then just stays there and does not move. The car does have a slight misfire and my thoughts are maybe is this is screwing up the air to fuel ratio. I found on ECS Tuning's site you can get a pair for $299. Next pay check I'll be ordering them.
