Causes? Solution? Driveway fix, or shop fix?

I love this forum, but searching anything out is next to impossible...too many threads come up. Wait is that really a bad thing?
Search "no bus".

What's the normal idle speed of a 4.0l. Mine fluctuates between 720 to 790 at idle.

Anymore the price is almost the same, get the Mobil 1, with a Mobil 1, MOPAR, or Wix filter. As far as "better" I hope you like reading, the can of worms starts and ends here, see ya in six months:

Will be going with Mobile1 10w-30 with either a Purolator or Wix filter. Any recommendations for synthetic gear oil?
