Will driving with p0401 code damage the engine in any way?
It is the EGR insufficient flow error... I was told it's purely for
emissions and that it's ok to drive with that CEL on. Does the
engine then run in "safe mode" with super rich AFR??

The hose nipple broke off the EGR selenoid... so dealer is trying
to get the part... so before that I would need to drive with that CEL
on...

Thanks.

 

mod: Sorry for the double post.. getting no replies from the other forum.

 

anyone?

 

vacum hose diconnected. Go behind the thottle and feel for a nipple. Then find the vacum hose right there also and conect them. Zip tie and your good to go

 

kreionic,

Thanks for the reply.
But it's not the hose... the hoses are in good shape (from what I can tell).. but the
EGR vacuum selenoid broke... dealer is trying to order a new one and it's taking a while.

So I'm wondering if it's ok to drive around with that CEL on... I've hear that engine will
run super rich destroying the plugs...

Thanks.

 

my car was running with that light for almost 3 months and no problem at all.....bit yea the car was too rich..no i got it fix was a freaking hose.will see tomorrow.

 

I dont know about it throwing it into safe mode but i know you can drive the car with it on.

 

The car will not run optimal.

 

with this light on, my car only made 212 on the dyno and before it came on I made 255.

 

My buddy ran with this light on for 6 months. His car seems to be okay. It ran really rich and he says the gas milage went down. We fixed it and now it runs well again.

 

with this light on, I have gotten amazing gas mileage for some reason.
