i got a trouble code that was saying egr excessive flow. what does this mean?

 

Mostlikely means that your EGR valve is stuck open. What are ya workin' on there (year at the least)?

*EDIT* - Never mind, found your sig in your profile. Please attach it to your messages.

 

its a 2000 blazer. 4.3 vortec 2wd 2dr 5spd. and i just broke my third set of motor mounts in 3 months and i dont even drive hard anymore........ compared to what i used to do

 

I recommend that you clean the EGR valve...

On the motor mount issue, what brand of mounts are you putting in? Have you made sure that the transmission mount is ok? Is there any binding in the mounts when you put them in?

 

im not sure of the brand of mounts but it was whatever the ones from autozone are. i replaced all the mounts and tranny mount at same time and still the broke.
