The engine finally threw a CEL, immedietly went and got the code pulled, P0400, EGR flow malfunction.

So, logically I should start by checking out the EGR valve? Where the heck is it on a 2007 2.3?

 

Anyone? Where is the EGR on an 07 2.3?

Sorry I'm really kind of flipping out about this happening to my new truck... lol

 

Check the EGR pressure sensor too. I have had problems with mine and swapped it out a few times.

Go to your local parts store they should be able to point it out to you on the 2.3

 

Ok cool. I'm thinking what happened was when the spark plug broke, a little piece of ceramic did fall in, but thankfully it blew out the exhaust valve, but found it's way through the exhaust and into the EGR valve, which is causing it to stick open, hence the rough idle and P0400 code.

 

Take the EGR valve off and try and clean it out. Re install it with a new gasket. And go from there. I dont know if on your motor the sensor and the EGR valve are connected if they are just go get a new one. But be ready they are not cheap bro

 

I'm having trouble just finding the EGR valve on the 2.3... lol

 

Dang this is ticking me off... lol. I know I'm problem staring right at the EGR but I just can't find it, maybe is it under something and I'm missing it?
