First off my Impreza is old, but it has been running great up until today. It is hesitating in the mid rpm range in 1st, 2nd, and 3rd gear. I have checked the MAF and the plugs and wires and all the stuff that a non mechanic can check, but I noticed something was broke. In the picture I am holding a tube that comes from the under side of the Air intake and broke from the water ever it is with the spring behind my fingers.
Any ideas what it is and why my car would be hesitating so much? I know I don't have much info, but ask and I will try and expound.
