3406b Not making hardly any power

Old and new ADR diaphragms. You can see the inside diameter of the old one is larger than the new one.

 

I wire brushed turbo pipe and turbo before installing and clamp. I disconnected all my intake joints cleaned pipes and boots and installed new clamps. Changed fuel filters. About to go for a ride and pull a hill. We'll see how it goes

 

fuel pressure guage would reveal a lot. Also look inside tanks for something that might block pick up tube. you never know what someone might have put in there!

 

Sounds like an Afrc to me.

 

I would think if something was restricting the tank it would be a lot more inconsistent. It's getting fuel steadily and when I press the pedal it steadily increases. So not choppy or spuddering. Changed both filters as well.

 

U mean the air to fuel ratio valve? Or ?

 

Yes air fuel ratio control valve. They are bad about getting pin holes. If you pulled the cap and found oil in it. It's probably leaking.

 

They restrict rack travel until the open up. If they won't stay open, you're unable to get full rack travel which causes low power

 

I bet that's it. There was substantial amount of oil. Temps are all fine driver has been running just fine. I have it scheduled to go in soon. I'll update

 

Well what did we discover?
