my 05 sti i bought a little while ago used. it was fine when i bought it but now when i push the clutch in and pull it out of gear when im about to stop or slow down, the engine will back fire and sometimes die. when im even going like 30mph. o.O
there are a few mods on the car all of which i did not purchase or install. a blow off valve, a intake and a exhaust system. any ideas of what it could be. it is at the dealer ship right now getting fixed the guys say it was the blow off valve not closing. im not to car savy and i wanted a second oppinion. and ideas would really help.
