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

[Zach Leahy]

Yeah, T-stat.   When was the last time you replaced the 1 wire temp
sensor.  they notoriouosly read too low when they get old.  Could be
that you are getting the engine way too hot due to a stuck t-stat, but
the gauge is not reading right.  If you are under the Blue lowest temp
reading when cruising, I think you need to get a new sensor.  They are
about $5 at AZ.  Do it with the T-stat, it's right next to it.
