OK because my car just randomly dies when i put the clutch in, other times it will just run roughly at less than 500 rpm. Also while at cruising speed it will sometimes feel like it hesitates, like slightly letting off the pedal an few times in a row for a little bit then go away. Any of these problems only happen about ~25% of the time but when it does its a real bitch in the city. I already replaced the MAF (it was used but i don't think it went bad this fast) and it seemed to fix it, only for about 2 weeks though. It came back yesterday...
