Need to know where to put sea foam besides gas tank and oil tank? How much to use on each part and which order to do them in?

Problem passing emissions. Code 0401 I believe. Says somethings wrong with the egr valve not getting good air circulation or something. I replaced egr valve and still wouldnt pass emissions

Ok, the sea foam will not help this code. The pipe on the egr usually get clogged and must be removed and manually cleaned out of all carbon. The intake side needs to be cleaned as well.
The last thing is the egr controls need to be verifed as you dont know if the valve is being commanded open.

Lots to this code. A number never identifies a bad part, just a failed system.

Ok, well what do you suggest I do? I have taken it to auto zone to have them pull up the code and all they said was type the code in to google and it will tell you what's wrong. Needless to say they were not very informative or helpful by any means

They are not techs, they are parts salesman. You bought a valve and that was there goal. Now it is your problem to have it repaired.
I suggest going to a real tech at a real shop to let them identify the failure for you.
