Got it, trying my best to solve these issues. I understand we need to validate the baseline before trying to mark off issues. - PCV If the new one could be leaky and have bad fitment, why is there no whistle or smoke coming out during a test? Why would a glove test not work on the 3.2 ? Why am I see...

I understand your concerns and comments. I my defense, the car was hot (drove to a further Shell gas station to get good fuel based on your recommendation) while I was doing this.

I think the lean code and LTFT are correct, from the 02 sensor it reads a lean combustion and therefore it keeps adding fuel to compensate for that. However 25% is a lot and indicates something big or obvious right ? ...
