I also forgot a small detail, the P0134 code is shown under "Pending Faults", it hasn't been confirmed as a "Logged Fault", any hints? thanks! ...I'll post a couple of pics from Torque in a few mins.

Whoa. Don't worry about pending faukts

Pending faults will sometimes show in time. Its just a matter of time once the cycle is completed.

...well P0134 finally cleared from the "Pending Faults" and was not elevated to "Logged Faults" so drove over to AAP and returned the O2 Sensor ...P0420 is still under "Pending Faults" ...and P0441 has been under "Logged Faults" for a sometime now.

Great! Happy to hear that! Let us know after 100 miles. . .
Every code removed is always good news!

...been up in Cloud 9 for while! ...replaced the Purge Valve on Sunday and have already rolled for over 100 miles and still the MIL light hasn't lit up, nor had I had any "pending faults", just the 3-Amigos are giving me company, but I'll get to that sooner or later, meanwhile I'm just enjoying being code-free or MIL-free ...think I dodge that "catalytic-converter fix" bullet! ...thank you guys for the help!
