96 Stang with issues

[badoo]

I just bought a 1996 GT with a 4.6 .
Besides being lowered, its stock.Here is my small list of issues:

1) The Mileage counter just stopped working , All the other gauges work. I checked the fuse and its good. Where do I start with this one?
2)The check engine light comes on and when I connect the reader, it tells me that the emmisions reading are hight or the emmisions are low. This just started yesterday. Along withthe code and light came a sputtering. Alomost like the engine is skiping or misfiring.like blop blop blop blop.

Any ideas besides getting rid of the stang?

For #1, I believe that there is a gear behind the panel which drives the mileage count. It should be fairly simple to replace from what I've read on here. For #2, I would start by checking the EGR, IAC, IAT, O2 sensors, etc... The reader does not give you a specific code though?

I'd be a little bit suspicious about the mile clocker not working,possibly been tampered with which is not good,worst case find a used cluster and just replace it.as for the sputtering and stuff have you done plugs or a tune up or anything to the car yet.start with the basics,you just bought the car and you never know how long its been since its last service,cant hurt to give it a good tune up and go from there.plugs,wires,fuel filter,pcv valve,clean the intake and iac,also clean the mass air sensor.

Answer for situation #1

Pictoral guide to odometer gear replacement It's a common thing to happen.

As for #2

Can you give us a specific code #? At the age of your car plus a guesstimate of your mileage, it is probably one of the items listed in the previous responses.
