i need to restart/fix my CAS AND ECU. how do i work with these parts?

 

Uh, what's the problem you are having? What do you need to fix? Why? Symptoms?

 

Overheating exahust. Engine is working to hard. Once engine gets a little warm it idles low then shuts off

 

Why are you assuming this is CAS and ECU related? Both those components are very reliable.

Have you:

-checked for vacuum leaks?
-adjusted the TPS?
-checked timing?
-had injectors cleaned and tested?
-checked position of spark plug wires, condition, and plugs?
-checked for clogged cats?

 

Well the CAS is making a noise that it didn't before so I'm assuming it needs to be checked. But I'll go threw the list of what u gave me. Ty.

 

Hm, if the CAS is making noise that could be an issue. Sure it's not the power steering pump or alternator? A mechanic's stethoscope helps a lot for stuff like this.

 

Yeah it's the CAS. It's spinning Off time which is making make noise.
