EGR Valve?

[quicksilverdon]

Where's the EGR valve?
I've never touched mine, and have a slight stumble. I just put in new double platinum Champions ($25 at NAPA), and the old ones were fine, nice light greay & gap about .042 -.044, so doesn't seem that was it. I already have Crane wires, so EGR seems a good idea.

Don,

I looked n my parts book and it shows the EGR valve but I still can't figure out where it's at. In the photo below from my parts book, the EGR system is 025-200 which points to the EGR valve. Maybe you can figure out where it's at. [:I]

Don, you know where it is! If you change the plugs then you had to at least lift the intake manifold up and out the way, right? Well, the "tube" on the back of the intake manifold (the one that has 2 bolts with different bolt head sizes) leads to the egr. [^]

QSD,
Email me and I scan my book for you. I'm not as talented as Crewzin.If I posted it they would be way to big

QSD,

I've replaced over a dozen of them on PTs.
The valve is located just above where the engine and transmission seam meets. Removal requires the airbox be removed.
There is the metal exhaust gas tube with 2 8mm bolts and a fiber gasket. The EGR mounts to the cylinder head with 2 10mm bolts and a metal gasket. There are 2 vacuum lines that go to the control solenoid, a black plastic pod moounted under the throttle body. It clips into the TB mounting bracket, and has a 3rd vacuum supply line and 1 electrical connector.
The EGR only comes as a kit, including the solenoid. The cost is under $65. Replacement takes about an hour to R&R the assembly, perform a drive cycle, and clear the codes.

Thanks everyone. I guess if I buy one, I'll figure it out by seeing it, once I have a new one to know what I'm looking for. [:I]
At least I know where to look now.
Took it for a test drive - seems the stumble is gone - will know for sure on commute tomorrow. - I'll hold off on ERG.

Never. Why?

I understand that if the PCV valve spring doesn't operate it can make the car hesitate and miss. It's easy to check and alot cheaper and easier to replace

Okay, where's that? Isn't it connected to rubber hose? Just haven't spotted it, but then, haven't looked for it. [B)]
Car seemed fine on way in, but PCV valve I've done on other cars - usually cheap and easy to do, so why not?
