Car stalls at 160 degrees

[jokeplayer]

My car stalls right now at the middle mark between 100 and 220. Sometimes it will stay on, but miss-fire and sometimes it will just turn off. It's a '90 RS 3.1L Fuel Injected. One friend thought it was the computer and another thought it might be the thermostat stuck. Any ideas would be great!

You might try checking out the computer. That is about the temp the computer goes into closed loop. See if you can get a code scanner that will let you monitor the engine with it running. Are you getting any computer codes?

I had my car do that to me and it was the distributor. You might try getting the ignition module in the dist. checked too, just to be sure. Most auto parts stores can do it for free.

BTW, if the thermostat was stuck it would just overheat.

Nevermind, just saw another post of yours that you have already replaced the ignition module.

Try taking the ignition coil wire off the dist. and hold it to a ground on the engine to see if you get a good spark every time. Then do the same thing taking the wire off at the spark plug. If you get misfire from the coil wire then you know your problem is most likely the coil. If you get a misfire at the spark plug then the problem is with the distributor. If there is no misfire at any point then the problem must be in the fuel system or the valves.
