It shouldn't effect how it runs, but you'll have a non-stop SES light.

Car will run fine without it but if the valve is left in and gets stuck it will make your car run like complete ***.

Either get a new valve or buy a block off plate.

Is the valve melted or is the solenoid melted?

Replacing the solenoid would be a relatively cheap and easy fix.

Replacing the valve on the other hand is more of a pain in the *** to get to and probably costs more to replace. If the valve is shot, might as well do what ss.slp.ls1 said and just remove the egr system completely and block it off.

Replacing the EGR valve is not difficult. All you need is a regular 1/2 closed end wrench to remove the two nuts holding down the EGR valve on the studs. Put the new one on with a new gasket and tighten it down tight. You should be good to go. I changed mine (once long ago when I still had emmissions crap on my car) in maybe 15 mins. It is hidden back there behind the intake and under the cowl, but just feel for the nut, slip the wrench on it and it will come off.

Buy a set of EGR block off plates and remove the EGR valve, EGR solenoid, and EGR tube. Then install the block off plates to the back of the intake and the passenger side manifold. Cap off the vacuum port that the solenoid used to connect to on the drivers side of the intake manifold.

Thanks for the Help guys especially that picture. It will come in handy when installing the block off plates.

ss.slp.ls1, I stand corrected.

I never knew removing the valve was easy. I removed my egr system while I had my intake manifold off to fix the dreaded intake manifold oil leak. I remember unbolting the valve and thinking, 'wow what a royal pain in the *** this would be if the manifold was still on the motor.' So I just assumed it would be a big production to get the valve off.

97Ztwenty8 - while your in there removing the EGR, you might wanna say f*ck it rip the AIR pump too. Why? Because f*ck emissions.
