I let the car sit for 20 minutes, and it is fine, until it gets to stop and go traffic again, then symptoms repeat. Car runs fine at highway speed though.
This car did this 3 years ago, but symptoms began at highway speed, not when arriving hot into city speeds. o2 sensor is fairly new, so might not be the problem.
Symptoms stop when Coolant Temperature Sensor is unplugged. (Small blue clip at front of engine). It could be either the sensor, the wire from the sensor to the computer, or the computer itself.
Is it safe to run with this sensor unplugged?
I am told the sensor should only operate when engine is cold, will increase fuel to mixture, and open the thermostat.
I need to go 1,000 miles with this car, can I unplug it and make the run?
I had to circle 4 hours back from Dallas today, back to E Texas, and I really really need to take this car 1,000 miles to Denver.
Hubby is diagnostic mechanic, but has no access to test equipment peculiar to VW, so cannot pull an error code up.
Have you ever had this glitch?
