What year and how many miles?

RE: code p2175
 

FSM is saying a low air flow/ restriction (slow accumulation) is being detected. Did you suck something into the intake??? maybe a rag??? Wouldn't be the first time that has happened.

From what you're describing, this could very well be what is wrong

Hemi's don't run well on munched cotton, well, none of the other engines do either, come to think of it.

I would check the air filter and clean the throttle body. Don't just spray the TB with cleaner on the Hemi motors because since the system is a fly-by-wire system all the gears and electrics are attatched to the TB. If the TB cleaner gets into them, it can mess them up. So, just clean it with a rag with some TB cleaner on it. If you must spray, watch were you are spraying. An old toothbrush can do wonders too.

I had the same thing on my 04 Hemi. The guy at the dealership told me to clean the throttle body with cleaner and a toothbrush. Carbon gets built up in the throttle body and restricts the plate from opening properly. It was causing my ETC indicator to flash and it would stall. I cleaned the throttle body which took all of 20 minutes and have hadno problems since. The power is back too. The airflow restriction from the p2175 is the throttle body not opening properly from what I understand. Hope you get things taken care of.
