If it idles too rich, you can adjust that on the ECU. You'll need a gas analyzer to tell though. If it runs too cold, the air sensor MIGHT be suspect, but I'd look at the thermostat first. Aside from the ECU and MAP sensor, much of the stuff under the hood doesn't cost much (parts that is) but in bulk, the amounts really add up. When I first got my 108, I stupidly cherry picked everything trying to chase down a specific issue. Turns out the timing was off, and I found this out after an ECU, MAP sensor, plugs, wires, sensors and much much more. Friggin' thing runs like a dream though ...
Some of this stuff is easily done in your own garage. Vacuum lines for example can be found at local parts stores. The air sensor and water temp sensors - same thing. You can probably replace the MAP sensor but without a gas analyzer, you wouldn't be able to adjust it, or see if it even needed adjusting to start off with.
