Plymouth Voyager Cold Weather Stall Q. I own a 1995 Plymouth Voyager, 3.3 liter V-6 engine and automatic transmission. Problem: Van will stall in cold weather. Originally, I needed to let the van warm up for five or ten minutes so that the van would not stall. Now, van will stall even after car is running after for ten minutes. I don't experience this problem when the weather is warm.

I've recently changed the coil pack, spark plugs and wires, and even had fuel injectors cleaned. The problem still persists. I've tried adding dry gas to fuel and problem still persists.

Stalling usually occurs when accelerating. The van won't turn off, but seems like it choking. The odometer needle drops. Diagnostic readings are normal. Any assistance given with this problem will be greatly appreciated.

A. The first thing to check would be the Coolant Temperature Sensor (CTS). Here's how.

With key off, disconnect connector from CTS. Connect ohmmeter across coolant temperature sensor. Resistance should read as follows; 700 to 1,000 Ohms at approximately 200°F (operating temperature). 7,000 to 13,000 ohms at approximately 70°F, (room temperature). If resistance is not within specifications, replace sensor.
