Thanks in advance

You can try to clean the EGR valve first.

 

remove egr and clean all the crap outta it.

 

Usually the intake hole is clogged.

 

I popped this code yesterday. Where is the EGR valve and which end is the intake? Do I have to remove the manifold to get at it?

 

EGR valve is mounted just underneath the throttle body. Remove the hose from the airbox to the throttle body... and then see the brass hose going from the rear of the engine to a funny looking part under the throttle body. That 22mm nut for that brass line... is connected to the EGR valve.

I would ask though... how does the EGR valve get clogged? Bad PCV system? If you are getting this code, then most likely oil is getting into your intake manifold, throttle body, flametrap, and EGR valve and gumming it all up. If you see this code, and clean your EGR to fix it... chances are the code will come back in 2-3 months.

 

or go with a 96 + ecu as they didnt have egr

 

Win!!!

 

Hmmmmmmmmmmmmmmmm. So you think I have a plugged PCV system? That's a little strange since I have NO SMOKE coming out of my oil dip stick. Is my system so clogged that it does not let smoke come out of the dipstick? I do think my RMS is leaking.
