New Civic VX membre from Quebec, Canada

[AlainB7]

I I'm a new member with my fuel saver Civic VX 1992

I have 3 question for you?

I presently do about 45mpg.

How can I increse to 60?

My civic VX has a major hesitation when I hit the gas.
Some times it actually bogs down so bad it slows down.
It only does this sometimes under 2500rpm. When the engine is cold, no problem.

Can I replace my fuel tank(10 gal) for a regular civic(13.5gal)?

Poke around on the site and you'll be up to 60 in no time. First thing I'd suggest is to make sure the vx is in tip top shape, that's the main thing that holds them back as they get older.

Sounds like you might need a new o2 (like everyone!).

You can prolly replace your tank but I feel like it'd be a pain in the *** for what it's worth.

But I dont have any Check engine light.

For the rest, the car is in great shape.
Dont burn oil, new cap, rotor, wire & plug, New K&N OEM size air filter and running on Mobil-1 5w30 oil.

How can I be shure the O2 is going bad, It cost a leg!

[SVOboy]

If you poke around TomO's posts he talks about it a bunch. Good VX guy.

Anyway, it seems a common problem on the VX for the o2 to just get lazy and not do it's best, but not quite completely stop working.

Look at it from the O2 sensor's point of view...It has to work in a 600°+ harsh, toxic environment all the time getting covered in combustion by-product and soot. Then when we're done abusing it we let it sit in the dark and freeze (compared to the 600°+ environment. Wouldn't you get lazy after several years too?

But I digress, lol. Anyways, check the Ebay for the L1H1 sensor and try for one that is about $180.

And thanks for the recognition, SVOboy, I try my best to provide good info for everyone to enjoy.

Alain - Welcome to the site, and check out the VX info and links in my signature, it will provide hours of reading and info.

Bienvenue a GasSavers!

You've certainly come to the right place for information about how to get the most from your VX.

[GasSavers_TomO]

I think this makes for 14 or so VXs on this board...WOOT!

Looks like you've got a great little VX there!

If the 02 sensor is original with those miles on it, I agree that it is probably the culprit. Did you use the specific plugs the car calls for with the specified gap? If not, I would switch to them. From my experience Honda's tend to run best on NGKs.

Car looks very good!

Yes. I only go to Honda dealer.

Even if I go to the dealer, I have to insist that I have a VX and the guy give me regular civic plug.
I toll him, Its a VX the plug are differenf from regular Civic. He check in is computer and tell me You're right, it not the same!

I have OEM plug, rotor, cap, wire, fuel filter.
The only non OEM it for the air filter. I buy a OEM replacement K&N

So il look like I will order a new Wideband sensor. What is the price at Honda dealer in US?

Welcome! It's always happy to see a fellow VX. My VX hesitates as well when I hit the gas, but not as badly as yours. I still haven't ordered my o2 sensor, but given the number of miles and the general neglect my car has had over its lifetime before it came to me, I shouldn't even hesitate to get one, right!? (I highly doubt it's ever been replaced)

I never gapped my spark plugs. They looked about a millimeter. Do they not come properly gapped out of the box? I'm using the NGK ones advertised on the car as the preferred spark plug.

About your lowish mileage Alain. What kind of driving do you do? If you could give a detailed account of the sort of terrain and length of trips and speeds and traffic you drive in, that all plays a significant part. At what RPM do you shift from 3rd gear to 4th for example? In third gear when I reach about 1600RPMs I shift. Sometimes sooner. About 1400RPM from 4th to 5th.

1st gear - 1800 RPM (or 11mph)
2nd gear - 1800 RPM (or 20mph)
3rd gear - 1450 RPM (or 25 mph)
4th gear - 1350 RPM (or 31-32mph)

That seem about right TomO? Any other VXers wanna weigh in on this?

I think I'm getting in the upper 50s Alain, (with no mods to the car and non LRR tires) although I'm still not certain about my mileage because I haven't done enough tanks yet.
