I don't have any code but I did find that my EGR tube is completely severed but will that cause the car to stall? I will be replacing them. From what I understand, an EGR simply recirculates the unburned exhaust gasses so I don't believe it will cause an stall issue. What do you guys think?

 

It depends upon the failure mode of the EGR tube. If the valve is stuck open and the tube is allowing external air into the intake system, then yes, things can run too lean, and that could in turn cause other issues (too many to get into here). That said, running too lean doesn't typically manifest itself as stalling.

 

A little more info please:

1. Where does the smoke come from?
2. What color is the smoke? Any particular odor?
3. Does the engine just turn off, or does it stumble before it stalls?
4. What's the temp gauge doing when this is happening?

 

Please see my answer within the quotes. Hopefullly I'll have some pictures for you guys of the EGR tube completely loose from its base. I'm having trouble getting the bottom peace connected to the exhaust manifold. Sprayed it with PB blaster and letting it soak for now. it's lefty-loosy, right?

I'm afraid that I've never even seen a V6 Honda engine so any advice I can give will be general automotive advice. Perhaps someone with actual V6 experience can chime in.

• It was dark and when the cop shined the light at it on the freeway...

So this happened just once? Have you driven it since? What happens if you just leave the car parked and idling? Does it still smoke and quit?

EGR feeds a bit of exhaust gas back into the intake to reduce combustion temps/NOx. It's unlikely that a disconnected and/or malfunctioning EGR would cause the engine to stall or smoke.

 

Agreed, I'm about 90% certain the stalling and smoking has nothing to do with any kind of a fault with the EGR system.

 

Just adding the "egr tube" set up - it is much like my old 3rd gen's.......just too bad you can't buy a new tube for the old 3rd gen's
