Ok. So today I got in my car and started it. It died. I didn't think much of it because it has done this before if I don't hold the starter for very long. Started right back up and away I went. I drove the 6 miles the post office, and six miles back and it was fine and dandy. Pulled up to the mail box and got my mail, went to pull away and a rattling noise started. Drove the car down the block to hear it more, and found it only did it when accelerating. Pulled into the drive, waited for it to cool some, checked oil, fine. No lights on, such as check engine, oil or anything. Started it back up, died again. Started it again and it revved up to 4, without me touching the pedal. It calmed back down and I put it in reverse to go see if it rattled again. As soon as I touched the gas it bogged down and died. Restarted it and it idled funny then died. Restarted it again, revved it right after, and let it idle about 2 minutes. Then it is fine again, but still the rattling noise when I push on the gas. Could my timing tensioner have gone out? The timing belt was replaced 10k ago (bought it from a local who fixes and resells totaled cars)... but I highly doubt he replaced this as well. Other then finding the factory didn't install my oil pumps gasket correctly, this has been the only problem. Does it sound right being the tensioner or would it be something else? My dad's a good mechanic, but my parents are separated and he lives an hour away or I would just take it to him, but I'm scared it will die or my belt will break. PLEASE REPLY FAST!
