I failed emissions with high NOx and HC.
And my car’s ECU didn’t throw a code. Anyway, it’s really hard to check since I have GM OBD “1.5” – those !^%#@%#&@&!!! Thanks GM!The basics checked out – clean air filter, fuel pressure regulator, plugs, wires, etc …
My O2 sensor (I have just one) was giving weird voltages at idle (+650mV). When I pulled it, it was UGLY – lots of white crusty crap.
That was probably antifreeze residue from before I put a new head gasket in.And I had some backfiring issues a couple of years ago.
SOOOOOOOO … all of that probably toasted my CAT.
I got a new one coming in about a half hour from now for $128.

Mine looks like the first one but also has a hex screw on the side – it has a clear plastic cap over it.
What is that for?
-Thanks

I agree sir, but until you get that “feel”, you need a torque wrench.
Big things like 10mm on up (mostly)- OK, go and get “feel” because you can’t break anything i.e. “Snug”. Below that … It’s too easy to strip.Not that I am saying you are wrong, but for us who aren’t so mechanically intuitive, it is a necessity.

Eric really likes that stuff.
I’ve been using high temp grease on my brake pins and lubing shoe contacts on backer plates but yet, Eric says use silicone paste.
Why?

I also use a torque wrench on small bolts and screws. Like a valve cover.
I once had a leaking thermostat housing. I kept turning turning the screws a quarter turn at a time trying to stop the leak. Eventually, I heard a “tink” when I stripped some threads.
Boy did I feel stupid!
I think a pound-inch torque wrench in quite valuable because unlike the bigger bolts, they are easier to strip.
And today with more and more aluminum, plastic and other cheap materials, torque wrenches are a must.

I’m convinced the EGR passages are clogged,….
Why?[i]
…while im driving, happens after the car reaches 55mph going down the highway at a steady cruise. [/i]
I am assuming that the car behaves itself at idle and slower driving speeds.If it is that erratic (surges and stumbles), I am inclined to think it is a PCM/ECU (Computer) problem or sensors. I don’t see MAP sensor mentioned in your post. Perhaps have that tested.
I would think a bad timing belt and bad valve adjustment would cause problems at all driving speeds, especially at idle – although I am not a Honda Tech.
