I have an interesting problem.I get a bunch of white smoke from the emissions box area. It happens a little after I start the car up. I only notice it if I let the car stands still.It smokes for a while and than it stops.No SES light and no performance loses.It just smokes up is all!!!
The first time I noticed it is right after I installed the Hypertech chip.
Now it happens once in a while. Not a regular thing. Seems to happen more when it's really cold out.
Anyone have this experience?
Any help is appreciated.

What do you mean emissions box? Theres all sorts of emissions stuff on the engine, maybe you could describe it from where in the engine compartment.

 

the area inside the car? heater-core, maybe?

 

The canister?

 

Sorry, shoud have been more specific.
I mean that black plastic box that sits on the passanger side of the engine.Not sure what it's called.

 

That woudl be the air diverter valve. I'd say take the plastic cover off and have a look. Maybe one of the hoses came off or it's cracked or something. Try to see where the smoke (or vapor) is coming from.
