1999 Jeep Grand Cherokee Repair Question
Car engine stops while driving...
1685 should not be related but 320 has to do with the crankshaft position sensor or camshaft position sensor. You have an engine running problem but didn't list the engine size. If your engine has a distributor, start with the camshaft position sensor inside it.
