The sensor is located on the left hand rear side of the block (near the bell housing). It is held in place by a 10mm bolt. It's to the right of the exhaust manifold (LH - radiator side) on the V6. Once you purchase the new sensor you'll be able to identify it on the engine. The connector to this sensor is located in the illustration.

SOURCE: power loss

Can't answer your last question but catalytic convertors that are just not working anymore won't cause any loss of power. However, if they have shattered inside (they are kind of a ceramic honeycomb) they can dump junk into the exhaust system that can eventually clog your muffler or resonator.
Checking whether this has happened isn't difficult; after the warm up of the engine, either you or a helper needs to listen to the exhaust note. If firing of the cylinders is still distinct, the system isn't clogged with shrapnel; if it seems to hiss at higher RPMs, it is likely clogged.
This effect is easy to miss; I've had two failures and when cold, the engine would pull fine because the chunks of ceramic would fall to the bottom of the muffler and glue together somewhat. Once hot and agitated, they would clog the muffler and cause a severe loss of power but the idle would be OK. A hill that I would normally pull at 70 MPH, I couldn't top at all; had to sit and wait for things to cool down before proceeding.
It also seems some engines appreciate a bit of back-pressure in the exhaust system because the car gained in mileage and pulling power for several thousand miles before the clog became critical causing the mileage to fall sharply along with the power.

Hope this helped.

4.6l engine. Why is the EGR valve opening between 10,000 and 12,000 RPMs?

Hi Bill
First off, here's a link that may help you. I think the main point is that once you've determined that the EGR is the problem, if you can't service it to get it to work, you replace it.

Regarding your engine RPM, 10,000 to 12,000 RPM is absolutely screaming fast in my experience. That's formula 1 and motorcycle race engine speed! Must be one wicked Lincoln.

I have a 1998 GMC Sierra, 5.7 liter Vortec 4x4. It has 160k miles. I have noticed that it idles at around 500 rpms when its warmed up. Not sure if this is normal. However, I have noticed a bit more...

The normal idle for your engine should be 550 to 600 RPMS so thats not to far off . But the fluctuation is more likely the crank pisition sensor then the EGR valve this engine has a condution called crankshaft wip witch is normal but going down a rough road can somethimes set off a misfire code It wouldn't be a bad idea to take the EGR valve off and clean it and check it but the CPK would give you the fluctuation in RPMS . It still could be a few outer things but this it the most likely cause

OBD2 "check engine lite" shows

Both codes are system too lean bank 1 & bank 2. First place to start is any obvious vacuum leaks. Look for broken,collapsed or missing vacuum lines. Check egr valve & intake manifold also.

I have a 1998 chevy c3500 with the 7.4 liter

you can't change the timing in this engine nor can you adjust the valves. The timing is adjusted throught the computer therefore there is no mechanical way to change this. You might be able to with some kind of programmer or computer program.

My car did the same thing. It was a problem with the EGR system, caused by the EGR valve opening too far when it shouldn't. Disconnect your EGR valve and make sure it is not stuck open. I removed mine and blocked it off with a metal shim and it solved the problem, so then I cleaned out the valve and replaced it and it worked. Check to see if it always cuts out at 3500 rpm or if its only when driving and not while parked in neutral. Also verify if it happens when the engine is cold too or only when cold, for example. Your EGR may be getting wrong signals from the EGR switch or from the EGR position sensor (EVP). You must verify that the EGR is the problem. If its not, it might be a coil problem loosing output at high energy demands. You also could have a fuel volume problem. At high fuel volume demands, the fuel quantity can't keep up. So you see, its a tricky problem to troubleshoot. If none of that worked, run the car at 3500 rpms and pull off each spark plug wire (one at a time) and see which cylinder does not cause a change in engine speed. That would be the problem cylinder and probably that fuel injector.
