Well like i said a valve train issue can make for some weird problems.
I am not sure if that is the same 3.0 that the taraus has but I chased a miss on mine for weeks and spent money fixing issues that really didn't cause the problem.
Get a leak down tester and eliminate that before replacing any more expensive "possible" issues.
The test is just time consuming and is way worth the not spending 500 dollars.
Not to say it cant be the pcm or whatever but i would try any free things i could
