Does anyone have the values for primary and secondary resistance for a 91 Protege? My car keeps dying once it's warmed up, and I suspect it might be the ignition coil?

Here is the values I just recorded for the car. Do these seem normal or off? thanks

Primary:

.11 ohms (ENGINE COLD)
1.0 ohms (ENGINE WARM)

Secondary:

11.95k (COLD)
12.4k (WARM)

 

Does the car misfire? Or just a really low idle speed?

A tip on checking these coils is, give them a gentle tap with a hammer( with engine running), if the idle drops or dips then replace that coil.

 

Thanks for the tip. I will try that!

Basically, the car runs and drives fine up until about 10 mins of driving (warmed up) then the engine will just die suddenly, while in drive (auto). It more often happens when I'm at idle at a stoplight than when driving. It will start right back up again but will die again randomly a few minutes later. The warmer the engine gets the quicker it will die until eventually it wont start back up again. If I leave it for a few hours it will start back up again and run again fine until it warms up.

The check engine light is not on. Sometimes the tach will move up and down randomly and quickly after the engine has died?

 

With that info, I would also look at the Cam position sensor. They play up when the engine warms up.
