'95 and older vehicles have a rather basic fault code system. I can help with the intake air temperature sensor, but first, start with the basics. Look at the spark plugs and wires if you have a misfire or rough running engine. The sensors just tweak the fuel metering calculations and aren't likely to cause a major running problem. Very often the only way to know there's a problem is by the fault codes.

Here's the page for the fault codes:
