> speedometer wont go past 70 mph,

could be mechanical, ends of cable unscrewed ?

>wont idle when cold,

clean the air idle bypass with carb cleaner will work like a champ

>temp gauge reads hotter when cold outside,

Thermostat is staying closed, which may be just fine

>check engine light stays on,

read the codes out, or have a station do it.

>air bag light blinks,

I have the same problem, intermittantly, anyone have a fix for this one ?

>runs good, factory original except off road H pipe &

If you have to replace the air bag module (behind the radio in the
dash), talk to Tim (aka Musttanguy). I got a used unit from him in
perfect condition for a fraction of what they cost new. Been perfect
ever since.

With that age and miles you need to start a systematic maintenance
schedule to replace and/or clean sensors, filters, actuators, gaskets
etc. Start with fuel filter replacement, MAF/throttle body/IAB/TPS
cleaning, general tuneup, cleaning electrical connections and applying
dielectric grease, transmission fluid/filter changes (drain the torque
converter too), cooling system maintenance etc. In my experience, the
Fox Mustangs are so damn dependable that over time the owners tend to
think they are invincible and long term, and short term, maintenance
isn't necessary. When this happens you start to see little annoyances
like the ones you state. With a little attention I bet the car will run
and drive like new again.
