I bought my 03 WRX about 2 months ago an have been storing it in my garage fur about a month an a half. I took mystock intake box out and cleaned all around it then put it back in, later replacing it with the turbo xs shorty. Since i removed my intake the first time i would go to start my car an it turns over fine an rev's to around 2500 rpm then quickly bogs down. the next time i turn the key it wont even turn over. if i give it gas while its running and it only stays under 1000rpm and sounds like a flooded snowmobile. what do u think the problem is...i dunno if the plugs are bag, its not getting enough fuel or what.....let me kno if u have had the same problem

 

is your maf turned the right way...it looks wierd, but the wires going into the maf should be pointed toward the front of the car. basically it looks like it's backwards. if it's not right, the car will do as whwat you said

 

Good call!! or check to make sure all hoses are tight and theres no leaks..I had the same prob. when i blew an intercooler hose.
