Thanks guys for all the help so far! And yes, it has DPFI.
So, my first fill up showed 37mpg and thats with about 150 miles with no muffler, a broken Cat and me relearning to drive stick.
I now have a new Cat, muffler back on it (can't believe the previous owner just cut it off!) and I'm getting the hang again of first gear (getting better at my starts while not revving the engine up to high). I'm really sad it doesn't have Tachometer in it stock.
I also put in a new thermostat (it didn't even have one in it when I got it) and will be putting in a new starter. It has been very finicky about starting once it's hot. AutoZone tested the battery and alternator as good.
Next steps:
It's also idling poorly, RPM's getting pretty low (almost to the point you think it will die) then corrects itself.
And I'll look into the MGuino. Looks like a good deal for the price. I'm just not seeing any instructions on their site or even the links they posted.
