I came to that conclusion because you and others said that the cap could be the source of the problem. I also tested the cap and the O-Rings are whole and intact but when performing the suck test, and getting a mouth full of fuel, it did not snap shut as expected.
Cameljoe, I did not know about the completing the monitors. Now that you mention it, and after a quick google search, it makes sense that it didn't pass emissions in CT after clearing the check engine light. I'm going to need to drive it around a little bit more to get the monitors completed.
Muddyspokes, I hope that I don't have to go to the great lengths that you went to to fix the problem. This Jeep just recently passed NH inspection and is now having problems with the CT emissions. What did you do after you replaced each component to see if it solved the problem?
Thanks all for your continued help.
