Well, it has been just short of a year since I replaced the EGR in my truck (lifetime warranty BWD part), and, guess what? The damned thing is throwing a code again. Naturally, it does this when I have my Mazda's engine bay torn up so with some in-depth work taking place. I'll be damned if I'm going to effect another parking lot repair on a hot engine (again). I don't have a need for a truck anymore, so I need to get off my *** and start cleaning it up for either a straight sale or trade for something different.

I've still been throwing an intermittent code for it. I'll get to replacing it one of these days.
I was looking up the parts on Amazon, and I read several comments that said the computers have a difficult time recognizing non-MOPAR EGR valves which is the reason they fail so often. Some have said they ran into the same recurring issue we were having, but once spending the cash and putting the MOPAR part on there they have been trouble-free for years. I'll probably just suck it up and get the real deal this time -- if nothing else it will rule out (or in) that theory.

RockAuto had (key word, HAD) four Mopar EGRs in stock, so I decided to bite the bullet and order one. $90 after shipping and the 5% discount. That's better than the $110+ I've seen everywhere else (shipping not included). I don't want to screw around with exchanging the Borg Warner part I already have.

I can't stand looking at a check engine lights if I don't have too.

Installed the new MOPAR EGR I purchased from Rock Auto. It comes with a new stainless steel gasket and new 10mm bolts used to secure the valve to the block. Be sure to save the 8mm bolts and existing cardboard gasket that routes the gasses back to the throttle body. I had to clear the codes from the PCM after the job was finished. I also had to shake my head the PCM had a code for what it called an improper grade of oil detected, which is ludicrous since I only use 5W20.
