I had overheating issues with it when I first got it because the previous owner took out the thermostat. Put a new 165* one in there and it ran great again. But it's almost the same feeling that it was when it would die then. I'm going to go ahead and get a 195* tstat anyways because why not.

What do you guys think? The needle reads fine, but the hoses feel rather hot to the touch...

Did you ever get this fixed??? Same symptoms and chasing as you have... Where does it lead???

Why are you replacing the CPS if it works fine? Prev. Maint?

Thats because BMW's are pieces of crap!!!

I put a new crank sensor in. Once past temperature the exhaust starts to choke the jeep out. Still no CEL

How do you know the exhaust is choking out your engine? Is your cat clogged?

Not sure what issue is. One up to temp it would run like crap, not idle high enough and it would run a cylinder down.
Replaced crank sensor.
Jeep runs up to temp and is alright but than if ideling it will go down around or below 700rpms and literally exhaust system is shaking sounds like its being choked. Only have the precats off the manifold. Cat on the pipe was replaced by a straight pipe years ago.

Any ideas?
