I removed the gauge cluster to try and clean/polish the gauge bezel and clean out all the dirt and crap that gets under the dash panel ahead of the cluster pack. Simple job to pop everything out, then 4 screws to remove the gauge pod. After I got it cleaned up and back in, I started the car and noticed I had a CEL. Started up fine and running smooth, so maybe having the pod connector unplugged has thrown a code? I switched the key on to roll up the windows but nothing else while it was removed. Check it tomorrow on my drive to work & see if it clears.
