Thanks for the add. I have a 2003 XLT 4.0 I just rebuilt this pig. Took me a year but I finally got the motor back in. I am having end of job issues, vacuum leaks, O2 faults (certified ford aftermarket) The new 02 sensors are a smooth universal 4 prong. I have open faults on both first stream sensors? Can I keep turning the connector until it is right? Thanks
