So I'm driving and I down **** and acs light comes on, can't change any modes and seems like it almost cuts power out. I pull over pump is making a loud *** noise, turn the car off and back on and I can am change all modes and turn the acs on and off but still seems that I can't get on it. I haven't read if a awc pump would cause that or not. Engine seems to rev but just doesn't go as before

 

Thought about over boost but stays right at 25psi a/f stays at 11.1-11.2

 

First thing you should do is scan your car for codes. A bad pump will not make the car lose power like you are describing. It is possible that your car over boosted and tripped a code, putting the ecu into limp mode. Scan for codes, write them down and then clear them to see if that helps.

 

I am pretty sure it was overboost since i pulled over turned the car off and the light went off and i can switch modes so i think the pump is good. However there are no codes. I hooked up my AP and everything seems fine. Even when it bogs the boost never spikes more then 26psi and my a/f stays 11.1-11.2 at wot..

 

What are yours mods? Are you tuned? Which AP map are you running? Need a little more info to help narrow down the issue. It may not work but disconnect your battery for 5 mins to reset the ecu.

 

mods are.
