got a dump valve fitted? if so remove it and put a standard one on for a few days to see if this sorts it out.

if it does, and you want a dv get a specific one for the car, iirc it needs to be a twin piston dv.

id try this before the maf as it could be either and this is the cheaper option

Emm I was just about to assume it's a wrx, not that this makes any difference to solving the problem.

Probably MAF

Take out your panel filter, give it a brush.

THen whip out the MAF Sensor & brush with Carb Cleaner & leave to dry.

I reolied my panel filter & for ages was getting hesitation, since I've cleaned the MAF no problem.

Once every couple of months I clean it goes great.

Good Luck.
