I have not yet tried using another object to measure the gap but I will as soon as I can!

As far as I know I connected the sensor correctly. I did not connect the female plug (coming from the sensor) directly to ground. The results in post 34 were from placing the multi meter directly between the 2 o2 sensor plugs. Yes, the connector is back in place as it was before. I remember a few months ago (6?) The check engine light came on for a day or two but went away before I had the opportunity to check it. Is it possible to reset the light to see if it will come on again?
