[Shotimes] Problem - My '95 MTX runs really rough when the engine temperatur e goes up.

[Wing D Lizard]

I had the same thing happen ( right after I got my ac converted,

but it may not have been related). 90MTX.

The shop replaced the thermostat.  I went to pick it up and after
3 miles it overheated again.

In my case it was the electronic fan that blows air through
the radiator.  as long as I was moving i was fine.  When I stopped
it overheated quickly.

The way to check is to switch your AC on -- it should turn on the
radiator fan right away ( regardless of whether the engine is
hot or not).
