threw a 24, 31, and 34... i've checked for boost leaks and fixed all that i found... now, the afm has always had problems in the plug area (it's been loose, and the connector on the inside of the afm has been snapped before... i'm gonna go ahead and assume that I should replace the afm... since all of these codes could possibly be the afm, and i've had problems w/ it before... also, if this is the issue, how poorly will this make my car run, as opposed to if it was functioning propperly
