white smoke from tail pipe?
Just started seeing some white smoke coming out of both tail pipes when I start the car in the morning. Usually lasts for about 30 to 45 seconds. Any ideas?
Thanks

if its only on startup in the morning, i'd say its just condensation in the exhaust...
do you drive the car in the morning, and then again later in the day? if it doesn't smoke in the evening after the car has completely cooled down again, I'd say its weather related and not to be worried.
Another cause could be a pcv valve, STFA for that.

Condensation ==> steam.
4.2s are also know for a puff of oil smoke, btu just a puff, and only if they were shut down still cold (e.g.: move the car across the driveway, put it in the garage...)
