1993 850 glt stalls sometimes at operating temp

[Gregg]

Hello I have a 1993 volvo 850 glt that has a haunting intermittent stalling problem it only occurs when the car is at operating temp and when the ambient temp is at least 70 degrees I have replaced the fuel pump and relay Crankshaft sensor and Camshaft sensor the only code it gives is ignition system rpm erratic #214 if anyone has any ideas please let me know
thanks Gregg

Welcome to MVS.
I hope you get an answer to your question.
You have looked at the things I would have looked at.
I'm thinking that at this point it could be faulty wiring from the RPM sensor (camshaft sensor)...look at all of your wires from the battery and that unit and see if you can back probe any electrical shorting or chafed wiring...

Check the proximity of the leads from the RPM (Crank) sensor to the ignition wires. There was a TSB that called for using a ty-wrap to secure the wires away from the high tension ignition wires. In its natural state the leads want to loop up near the coil wire.

Gregg,

Your post is a few years old but I don't see a resolution. I am having the same problem with my 1193 volvo 850 glt. Did you solve this problem?

thanks,
Nancy

I think I have read on this site that the temperature sensor can cause interferences with critical systems. Maybe someone else will add more to that.
