I have a 2002 WRX 5-spd Turbo (all stock) (90K miles) (not STi) which has been sitting in the garage for about 3 months (was on international assignment).
Came back and noticed that the turbo does not seem to be kicking in. Usually, over 3000 rpm the car lunges forward. Not any more.
Are there any simple checks to see what could be wrong. Prior to my trip I had done a $500 AC leak fix ... so kinda tight on funds.
