Thats good to know. Who produces those?

I never thought I would be happy to go back to stock.

Stock intake pipe and new K&N filter


For those curious, DX vs VX intake pipe


Inlet size difference


Ricer intake


K&N installed


Back to stock goodness

Wow. The airbox and intake tube design on the next gen DX was quite different.

Took it for a drive this morning, idle seemed off, it would reach about 800 or so then work its way back down to 550, but not sporadically, very smoothly. Went through the steps from scratch to re-adjust the idle, also removed the throttle screw from the body out of curiosity and cleaned up the mounting hole and the screw/plug itself. Drives fine, but for some reason I feel there is an intermittent misfire. The plug wires are the only thing I haven't replaced so I may do that here soon. I noticed there are different part numbers between the VX and DX wires so there is some kind of difference there, I wonder if someone put DX wires on here and if that could cause any issues. However, I will say that it seems the stock intake gave back a bit of low end torque that I felt was missing from the huge intake that was on there previously.

Next on the list is a new OE heatshield for the exhaust manifold.

Anyways, caught a better picture of the engine bay during the daytime and a random pic of the car itself.

Reposting this from a tech thread I made in the OT section just to keep consistency with my ongoing maintenance/diagnostic stuff.

http://ecomodder.com/forum/showthrea...oid-32384.html

So after some reading, and quite obviously, this solenoid valve is a part of the evap/emissions system with the charcoal canister. Some have stated that without this valve the car could potentially run rich or develop a smell of fuel. Removing it will also negatively affect gas mileage.

Like I mentioned before, the previous owner removed the one on this car for whatever reason, as well as the other charcoal canister lines.

Before, nothing there but the screw, vacuum line hanging below, plug freely hanging (looks identical to IACV connector but different colored wires).


The valve, which for test purposes, I picked up at Pick-N-Pull for $5. I figured it would be worth the few dollars compared to the $130 price Honda wants for a new one. Also not even sure if it matters, but the top "dome" looking piece is a filter that clips into the valve, it's replaceable and costs $9 from Honda.


Installed with connector back in and correct vacuum hoses, the top nipple connects to the top port of the charcoal canister, the bottom nipple connects right below to the intake manifold.


Followed the diagram here for the vacuum lines:




I am a little disappointed that this did not get rid of my occasional idle issue where it will drop drastically low or sometimes stall. My idle is not sporadic, so I figure it is something small but I have determined there are no vacuum leaks. Will be replacing the map sensor here soon to see if that helps.

I will say though, that the car feels a little smoother at idle. Will it improve my fuel economy? We'll see come the next few tanks.

Didnt think i read this anywhere on the thread but how new is your o2 and is it the updated correct 5 wire one? I bought a new one and it made a hell of difference. also a valve adjustment helped but not as much as the new o2.

It is a newer 5-wire put in not too long ago by the previous owner and I confirmed it was the "correct" one based on the number that's stamped on it.

welcome

Belated welcome to the forum!

Lowered VX with HX wheels - I haven't actually seen that before. Looks great!

And low = good for MPG. HX wheels are also good if you have some good LRR 14's on there.

Congrats on getting a VX! That car looks really clean! Good luck on your idle issue. I know mine stays pretty high on initial start up and then mellows out after its warmed up a bit. Also when I disconnect the battery for awhile and reconnect it it seems to take the Ecu some time to relearn everything and smooth out the idle.

Metro, is this sarcasm? I actually can't tell... Lol.

OK, second VX with HX wheels.

(Not kidding about liking the look though.)
