Hello!

I am completely new to wrx and the turbo game so I hope it is ok that I ask a few questions. I have a 2001 Impreza Wrx, which seems very good. But it is a couple of things I am wondering. From 0 rpm and up to 2500rpm, it kinda seems jerky sometimes. It goes, but stutters if you know what I mean. I havent driven a turbo before, but maybe the turbo lag is that bad? It is of course worse when its cold. Also when I am at a stop sign, and gives it a few rpm ,it almost jumps down to 0 rpm when i let of the gas. It have actually stopped when I was in traffic cause of this. The engine is all stock, only decat and exhaust. Ive had Honda Type Rs and Celica T sports and other high revving cars, but all of them was much better to drive in low gear and traffic. But like I said, maybe its just me not used to turbo cars.
I am from Norway, so there might be some errors in my english

Thanks!

 

Check the idle air control valve.

Im doing mine this week

 

Ok, I will check this on monday, I have ordered a gasket as I heard this could crack when cleaning the iacv. Will let you know how it goes

 

definitely not normal. likely IACV or MAF imo.

 

Ok, I have cleaned the MAF sensor, made it a bit better, but hopefully its the IACV. Glad that you say that, because then I have something to look forward to when its fixed
