I am not sure what thermostat I have but I do not the 185. My temps are at the mark between 100 and 220. There is one mark inbetween the two. Should I put a 185 in it. I wonder if that hasa anything to do with the weird idle problems and stalling at stoplights?

I believe that stock for both the V-6 and the duke engines are the 195*F thermostat. Running without a thermostat may cause weird idleing problems as the ECM won't go into closed loop operation, or take quite a while to do so. The thermostat should have a number on it on the end stating what temp is.

Edit for a clarification.

I know it doesn't get to 190. I will go and get a new thermostat and replace it. Should it be a 185 or a 190?

I checked it and the only # I could find is 180. There are some other numbers but that is the only one that resembled a temp.

Factory thermostat is 195°F. It's a standard temp and design so should be available everywhere. The Fiero temp guage is notorious for being inaccurate, BTW.

What one should I run? Should I replace the 180 with a 195?

I stand corrected, yes replace it with a 195*F thermostat

The ECM's fuel maps are designed around the 195°F opening temperature. Modern seal technology means there's no benefit to running a colder thermostat in a properly functioning cooling system aside from the placebo effect of seeing the guage read lower. You'll get your best power and efficiency with the 195°F thermostat in a stock motor.

Well I got my wife to stop and pick me up a 195. I will let you know how it does. I just hope it straightens out my stalling/idle problem.
