94 3vze XCab 31.5" tires (265/75R16) 4.30 Automatic Trans, rebuilt 1000miles ago. I only get 10mpg (11.3mpg accounting for tire diameter).

Plugs and wires are new, injectors were not cleaned.

Is there anything that I can do?

When, if ever, was your O2 sensor changed last? I'd start there first.

Probably never, but it has been tested with a multimeter per the FSM.

I read your stats, then looked at your display photo and thought, HOLY CRAP those are NOT 33's, then it processed in my head what I was looking at........

Not quite as quaint as the 12 inches equals one foot deal, and three of them to a yard. Then there's 5280 feet to a mile. Or freezing at 32 farenheit and 212 degrees for boiling.

Nice system.

And by the way, I get roughly 12.5 liters per 100 kms. Which would be approximately 22.6 miles per Imperial gallon, or 18.82 miles per US gallon.

As you can see in my sig line, I'm running a 3.4 liter engine with 265/85R15...er, 33"x10.5"x15" tires.

My calculations also show that 8 out of 24 posts, as of this writing, are by Canadians, giving you 33.3% (or 1/3) of the posts from Canada, not the 90% you claim. Don't forget the 1 guy from Belize, which is not part of the US.

Hahaha!!!! Well said.

google it HHO generator you can build 1 or buy bad thing is it messes with ur o2 sensor and map so you got to work around them.I will be selling them in bout 2 months but if ne1 wants make 1 and neeed help you can ask me Qs.Basicly its LYE AND WATER

I've heard many times that HHO is a scam. Even if it wasn't, there is no way you could get an increase of 200% in fuel economy. I wanna see some pics or some kind of proof. Otherwise, you're trolling

Exactly. I tried it and then got $100 deep and went, "wait, what am i doing?" because...

"Energy in a system may be transformed so that it resides in a different state. Energy in many states may be used to do many varieties of physical work. Energy may be used in natural processes or machines, or else to provide some service to society (such as heat, light, or motion). For example, an internal combustion engine converts the potential chemical energy in gasoline and oxygen into heat, which is then transformed into the propulsive energy (kinetic energy that moves a vehicle). A solar cell converts solar radiation into electrical energy that can then be used to light a bulb or power a computer.
The generic name for a device which converts energy from one form to another is a transducer.
In general, most types of energy, save for thermal energy, may be converted to any other kind of energy, with a theoretical efficiency of 100%. Such efficiencies might occur in practice, such as when chemical potential energy is completely converted into kinetic energies, and vice versa, only in isolated systems." - http://en.wikipedia.org/wiki/Energy_transformation

so what you are saying is that you have 7-10hp to turn your v-belt, which runs an alternator (which would be the first transducer) that converts kinetic energy into electricity, which charges your HHO generator (the second transducer) going from electricity to stored kinetic energy of a combustible gas and then burned in your internal combustion engine. now its math time. ill give you the benefit of the doubt and say you are pulling 10hp to run your alternator. then through the first transducer (ill give you a 100% energy transfer [no loss at all] which never ever ever happens) then into another transducer (also 100% transfer in this case too) into a combustible gas that, when burned in an internal combustion engine (ICE), has been revered to the one of the most inefficient powerplants. To loosely quote Corky Bell's Maximum Boost, of all possible energy of combustive gasses in a ICE one third of energy turn the crankshaft via pistons and rods, one third is heat loss out the exhaust, and one third is heat loss through the cooling system.

So your 10hp you started with is down to 3.333333HP actually helping efficiency.

So that being said, use the heat loss out of your exhaust and put a turbo on it! it will be more efficient as well as more power (power is a characteristic of efficiency.)

I'll get off my soapbox now.

Doesn't a cavalier get like 500 miles to the ounce anyway?

Oh, I get it, this is a sales pitch, '...I'll be selling them in two months. . . .' because I would TOTALLY buy something from someone who took a month to build something the first time, made one other one and is now going to try to punch the item out on a commercial sales level. Just sayin. . . . pics will make the difference here I think...

My vote for the fate of cncrestoration:
On a side note, I think someone should start a thread on this is we want to debate so we aren't jacking this one
