EGR check engine

[driftn1g]

Ok i get a EGR check engine light on all the time.. is this bad to run the car like this?? and where is this sensor at?

Is the EGR system different on 94's? every DSM (90-92) I have worked on I have always disabled the EGR systems and blocked it off with a plate. No CEL.

If your EGR system is broken, you may want to consider blocking it off with a plate.

I do not believe that any harm can come from your car with a stuck open EGR system, although a car with a stuck closed EGR system is what is desirable.

I have an extra EGR valve if you need it.

The EGR valve is located on the passenger side of the intake manifold near the battery tray. Check the vacuum lines running to and from it.

Well you'd have a massive boost leak if you have a failed egr system.

One a 1g the actual solonoid is mounted on the intake manifold and is acuated via vacumm.
The solonoid is located on the firewall.

wait.. that makes sence, cuz it use to go on and off, mostly stay off.. now its stuck on after basically not caring and running my car with knock... now that leak is fixed but its still on.. i can clear it with the logger

If you blocked it off you might as well yank the solenoid and vacuum lines. Clean up that engine bay.
