Update: Had another problem. At some point I guess the exhaust hanger mount came off (I only had one on, there's supposed to be two). The weight of it caused the left muffler to fall off. The whole exhaust scraped against the ground for awhile, and caused a piece to break near the exhaust hanger. I jacked it up and the area where the bolts connected the exhaust together broke (A friend of mine who was driving behind me said he saw a piece fall off when the exhaust fell off). I bought a 1 7/8" exhaust connector and connected the two pieces together, put the left muffler back into place, reconnected the exhaust mount, and got a metal strapping kit to give the muffler some extra support to make sure it doesn't happen again. I'm going to get another rubber exhaust mount and some JB weld to seal the connector, but it's doing a pretty good job so far. No loud noises or noticable leaks anymore, and only $6 for the exhaust connector and metal strapping kit.

Anyway, I had the car jacked sideways, and when I put it back down and checked everything, I noticed some coolant leaking. Looking under the hood, it looks like the water pump is leaking. When I give it gas, coolant spurts out near the water pump. I'm not sure if it's related to having the car jacked up, I'm hoping I don't have to replace the water pump, but it's starting to look that way.

Ahh well, I've only spent $46 so far fixing this thing. My dad's car needs a freon charge, so we're going to split the cost for that and I'll end up spending about $13 for the freon and the gauge. Just hope there's not a leak, but with my luck I'm sure there will be. Still debating whether or not to use stop leak. I've heard bad things about it, but I doubt it'll make things any worse, compared to most of your cars mine's a Grand Prix of crap.
