Hi, first post, yay! This forum is a real treasure trove, so thank you all for keeping it alive.
I have a problem with my 1997 Jeep Cherokee, 4WD, 4.0, Auto, NV242. I did post it on two separate forums, but no luck. My local mechanic also has no idea.
The problems:
1. Slight fluctuation of RPMs in idle, barely visible on the gauge.
2. Shudder/vibration while in idle.
3. Lack of power in the low range (but it might be my imagination).
4. 10-12 MPG highway/city. Conservative driving.
5. New one, last 3 days: weird start when it got cold outside.
I have a video of a start and idle here. The problems are not that visible, but it might help. The RPM problem starts at 0:55. I did try to catch the shudder but no success.

What was done:
1. New plugs, wires, distribution cap and rotor.
2. New manifold gasket.
3. Checked for vacuum leaks, but no idea if done right.
4. New IAC.
5. Cleaned connectors for O2, TPS etc.
Thank you very much for any help rendered .
