[s-cars] urs6 Hesitation When Cold

[Fred Munro]

Tom;

Check the oxygen sensor heater and heater circuit. If the heater isn't
getting power, the sensor won't read right until it warms up from exhaust
heat. When I bought my UrS6 it had a hesitation when cold - the O2 sensor
was bad and replacing the sensor cleared up the hesitation.

My '95 S6 w/58 Kmi has developed a hesitation when cold.  It's fine when it
warms up in 5-10 miles. It has fresh plugs. One troubleshooting tip I saw
said check the Coolant Temp Sender (G62) I did that, Bentley say's it should
read 1000-3000 ohms at 68 degrees F and it reads 1800 ohms at 75 degrees.
Any other ideas. All std maint. Has been performed air, oil & fuel filters.
TB, etc.
