I need to get to the egr valve, but I hear it's under the Throttle body, (1994 850, Non-turbo)
Guys,
Alright, I did the flame trap cleaning and my Low EGR flow check engine code is still on...The car is running like butt in the City but fine on the interstate...I'm guessing the egr valve is staying open in the city...where is the throttle body/egr valve on a 1994 850 non turbo...any pointers would be great too...
Thanks,
Joe

It is on the bottom side of the intake manifold just behind the throttle body. Check the vacuum lines to and fromthe EGR controller first. The controller isjust belowthe top of the radiator shroud towards the center of the shroud. There is usually a hard plastic line that goes from the controller to the EGR Valve and it has rubber lines at each end. The EGR valve end tends to get hot and break
Chances are the valve itself is OK and cleaning it with carb cleaner will get it working just fine. The hole that goes through the intake manifold also tends to get completely clogged. I fixed my son's EGR problem while I had the manifold off servicing the PCV system which made it quite easy. I'm thinking that you can clean the hole without removing the intake manifold but it will frustrate you. You will need tounbolt thevalve in order to do it.
Removing the valve is a challenge (particularly the inboard bolt) due to the depth of the bolts they use to hold the valve on and their proximity to other stuff.
Good luck with it.

If you read the owner's manual, the EGR valve is actually a routine service item; I believe it has to be inspected at every 60,000 miles and cleaned 100,000 miles.

To do it really right the intake manifold needs to come off. Having done it once before I think I could get it done in2 to 3hours in the driveway. You will need a new EGR gasket and a new intake manifold gasket. For the work involved the quoted price seems more or less in line. Hopefully the EGR valve can indeed be cleaned, I think it runs nearly $200.00 by itself from FCP or eEuroparts.
Look around her and other places for writeups on PCV servicing and it will give you a lot of the steps involved.
