Yeah, the traction control does work. When it was wet, and the TC was on, if I floored it, the wheel would start to spin, and then the TRAC light would start flashing and it would cut the power and stop spinning. With it off......
......it would go sideways real quick.

I had a thought. That part of the plastic intake that goes from the battery to the air filter seems really restrictive to me. If I removed that part, would it affect mileage? I'm conflicted about it because while you wouldn't be channeling in air directly from outside, but you wouldn't be as throttled either....

I don't know if it would help with any mileage but the bad thing of doing that is you'll be sucking in hotter air b/c more would be coming from the engine bay area. And also you'll have a better chance of the hood insulation getting sucked down and just blocking off any air coming in. That's happened with a couple CL members and it took them forever to figure out why thier car was running like crap, unless the hood was open. I wouldn't change it, not from there anyway. Even cutting an opening in the filter "box" and using a K&N you're still getting hot air in. I would leave it alone. But, if you wanted to try it, it wont cost you anything. Free is the best.

I'm going to change my spark plugs today and see what happens. I'll try and get a picture of a new and old plug next to each other for comparison. Hopefully this helps, or i'm going to be kicking myself for spending $40 while i'm still looking for a job.

Well, it's been a long day. Got everything taken apart, put the new plugs in and fired her up. Started missing and wouldn't go over 2,000 rpm. Started diagnosing and found out that there was a hole in the head on the wire for the driver's side coil. It was arcing with the line from the coolant overflow. A new set of spark plug wires later, it runs like a charm. We'll have to see how it runs now. The old plugs were looking pretty bad.

The thing is, I've never pulled off that coil wire. I hate those plastic clips on the wire where it connects to the coil. So brittle. At least I know the plugs and wires are all new. The plugs were autolite(budget restrictions, or i would have gone NGK). Cost me 37.80 total for the plugs. Wires are the only thing available in short notice on a Saturday afternoon, Prestolite. I don't know anything about them, but I had to pay $100. No other choice. I had to GTFO this afternoon and couldn't get anything elsewhere(other than ebay, but would have been waiting a few days, out of the question).

Had my first city only fillup. Put in 6.563 and travelled 85.6 miles, giving me an average of 13 mpg. My previous city fillup had netted me 11.9 mpg. I don't know if the improvement is because of driving style or the spark plugs + wires.
I'm going to run this tank down to the 1/4 tank mark so that I get a more accurate reading. It'll probably take a couple of weeks though, since i'm trying to cut back severely on driving. I'm also going to start filling up at better gas stations. I've been going cheap and filling up at Maverick since I moved here for school. When I was still at home, I filled up at our local Silver Eagle where I worked, and i've since heard a lot of people complain about their fuel. I usually let price drive my fill-up. I'm going to start trying Shell or Chevron.
I noticed that my mom's 91 LS has 205/65/15's where mine has 215/65/15's. The size difference is noticeable to the eye. I wonder if this is the reason her car gets better mileage than mine does. It could be that the bigger tires cause more drag and cause my fuel mileage to go down. Or...I could possibly be getting better mileage and just not be seeing it because the speedometer could be off. Who knows.... Regardless, these tires still have a lot of tread left on them, so it'll be a while before I replace them.
One last thing, I've run seafoam through the crankcase and the fuel tank. I have not yet sucked it through a vacuum line on this car. I am curious which vacuum lines you guys put it through. Would one of the 3 lines on top of the throttle body be fine?
