It’s going to surge/buck regardless what you do because of lack of power and tunning.

You ignore a bad OPDA at your own peril, since failure to replace this relatively inexpensive component will result in lack of sufficient lubrication and eventually catastrophic engine failure. The repair is a DIY repair for any hands-on type of person without the need for any special tools.

What should the thermostat be on a Jeep Wrangler?

The job of the thermostat is to monitor the engine temperature and engage the fan once it exceeds operating temperature. The Jeep Wrangler 4.0 has a cooling system that requires a 195 degree thermostat. Anything lower than that can trigger the CHECK ENGINE light. It should activate automatically as the engine temperature fluctuates.

What to do when your quadratec engine gets hot?

The Jeep dealer said the fix was to install some insulating material between the injector rail, and the intake manifold. That did not fix it.

Why do you check both hot and cold transmission fluid?

The reason for checking when both hot and cold is transmission fluid expands as it is heated.
