100rpm??? theres no way itll turn over........

revving it letting go and dodgy idle speeds usually lead to clutch problems but im no expert......

just putting in ideas since no1 has replied!

have you disturbed the MAF sensor - dropped it or anthing like that?

Symptoms sound like a knackered MAF. Why take the airbox off - you fitting an induction kit.

What model impreza have you got?
Could well be the maf if its only happened since you taken the airbox off..
Either that or coils, plugs, or maybe idle control valve

Connect the two jumpers together under the steering wheel ect...
