Default EGR Valve

My service engine soon light comes on once in a while, the computer said its the EGR Valve. How difficult is it to replace, and approx how much do they cost?

They aren't that hard to replace just two or three bolts and the EGR gasket. Go to the local library and copy that part of the chilton manual if you don't have a copy.

I think they are around 150-200 dollars but i am sure DeathRat knows for sure.

I can copy and email you the procedure if you want, but I gotta ask, do you have the digital egr valve with the black plastic cap like mine? Check my website if you're unsure. If it'* like mine, one of your solonoids may be sticking....actually, it'* the shaft and spring that stick on one of the 3 positions. Squirt some lube on them, and it'll probably fix itself. DON'T use WD-40. It'* really nothing but a solvent, and will evaporate from the heat too quickly. Use some type of Teflon spray. I bet your prob will go away.

Just make sure it'* the ACTUAL EGR Valve & not the EGR Soliniod first or all that money will be wasted for nothing!

I didn't have to take mine out, didn't want to, it was hot when I read my codes. If you do, though, you can do a more thorough job.....you can manually move all the springs and shafts while lubing. Use a light oil, like something with teflon......anything will work, but WD-40 due to the evap problems associated with it. After you get things moving freely, you may want to apply a light hi-temp grease. If you have an electrical fault with one of the 3 solonoids, this won't help you, but if you have a mechanical bind, it will. That'* what was wrong with mine.

Hey Will, can you send me that procedure? I'd really appreciate it, I've never dealt w/ anything like this before. Thanx

First, tell me iff your EGR valve looks like mine in this pic, so I know if you have the Digital or the Linear valve (just at the driver'* end of the fornt valve cover, between it and the airbox):
