How much gas was in the car?

gas gauges are not always correct. Fill the car up reset the odo. and check the fuel mileage the proper way.

between a quarter and a half

and i will do that when i get the money to fill it up

[93.4dr.22A1]

odds are your cars gas mileage is fine. Alot of people have that issue. the floats get sticky, and dont function properly. My car does the same thing, I can go bout 200 miles b4 hitting the halfway mark, and i'll be lucky to make it 100 miles below it.

timing belt,adjust valves ,o2 sender not bosh ,honda trans fluid,check brakes- make sure they are not dragging,alignment ,plugs,cap&rotor,,,30mpg is what you should get

word
i was planning on doing most of that when my check gets here
NTK O2 sensor

I'd do like 93.4dr.22A1 said, fill it up and get a more accurate measure of your mileage. Once you have this info, then make the other adjustments (O2 sensor, etc), and you'll see how much of a change you actually made.

cool i go a little nuts on my cb ...lol it`s got 112,000 on it..a 90dx....o and most important new thermostat

[tm123]

tire pressure was around 40 on all 4's!!!
i havent checked it since i lowered it maybe that did it
but its at 30lbs
the door says 28
this could have led to a disaster

Well what I would do, is check your fuel filter, plugs, wires, air filter, and O2 sensor, cap and rotor.

Also pay attention to how many gallons your putting in, and reset your ODO, and see what your gas mileage is.


As stated above are cars gas gauges are not that acurate. lol.

How horrible is your gas mileage?

22 - 23 MPG is average. Any mpg below 22 is horrible.
I suffered 17MPG on my CB7 because it was running very rich.
You can even smell the unburned gas on the exhaust.

Some unmentioned factors are:

- Clogged EGR ports
- Clogged cat
- Mafunctioning spark plug wires
- Incorrect igniton timing

Check all of the other fellow members said and follow these also.

PS: You cannot clean an oxygen sensor. These are extreme sensitive components that don't want their tip to be touched by anything.
Recommended replacing the sensor instead of cleaning it.

busted high pressure fuel line?

yes i found that out by asking my auto teacher this morning
and how would i go about cleaning egr ports/valves
they shouldnt be bad since i only have 84k miles
wires and cap are from 91 but have new ngk iridiums
found out in that process need new spark tube seals
thanks all for the advice

You would have been fine (Unless the tires are incredibly old and shot). The door jamb recommends 28 lbs for ride characteristics but the tires themselves have a much higher max tire pressure listed on the sidewall. Check it and see. Although 40 is on the high end I agree. I run my tires at 30 psi dead cold front and rear. (I use a bicycle pump to adjust the pressure in them after the car has been parked overnight and it has been out of the sun).

I get 30-33 mpg on my 92 DX manual but autos get lower (in the mid-twenties is common).

Following the others' recommendation, fill the tank up all the way, drive 100-150 miles or so, then refill and see how much gas you actually used. Hopefully you don't actually have a problem.
