I really hope I'm losing my mind, but it feels like my 2002 wrx is losing boost. I noticed it today around 2pm. I started at my wastegate control arm and it is kinda rusty and didnt want to move much. I hit it with some PB Blaster and now I can move it back and forth. But it still feels sluggish where it used to put me back in the seat a bit. Wondering where you guys suggest me starting to hunt down the problem? Vacuum hoses look ok. You think UP Pipe? Or could it still be the wastegate? (First turbo car owner freaking out here)

Do you have a way to monitor the boost pressure?

Not at the moment. I got the car a little less than a month ago. Just noticed today though that I can actually hear the leak from inside the cab. Going to have my bro rev it to boost and listen and try to find it when he gets home.

Find a way to borrow an OBDII scanner and we can help you with datalogging.

Please don't start messing around with the wastegate arm for no reason. It was set the way it is for a reason. If the car isn't running right, there is a reason, and it isn't likely that the wastegate arm somehow moved out of the blue.

I didn't move it (like disconnect it) I simply made sure that it wasn't stuck in the open position

No, I try not to do anything to my cars that I don't understand. While I understand the basic concepts of a turbo, I dont know the little intricacies just yet so I wouldn't attempt that without an experienced persons help

FOUND THE LEAK! One of the connectors was brittle and had split. Definitely getting all new hoses and connectors now!
