I can smell electrical smoke after engine has been running

Hi,

The EGR does have an electrical connector, so it's possible. However, I would think you would see at least a small amount of smoke.

If you look at pic 1 below, I circled a part on the EGR that gets extremely hot. Make sure nothing is touching it.

IF you decide to replace it, here are the directions. It really isn't too hard of a job. The remaining pics correlate with the directions.

Is it possible to open the hood to see if you can tell where it's coming from?
