set timing

i have a 90 honda accord the problem i have is it is running ok but it
seemes to be using too much gas i put new plugs in it denso plugs parts
store didnt have ngk the compression is ok. i just pulled one of the new
plugs out and they are black not tan and it is not oil fouled i want to
check the timing but it says to take a wire and ground it before i set the
timing where is this wire also a budy of mine said that a bad o2 sensor or
a bad temp sensor would cause it to run rich like it is. there is no check
engine light on

 

i forgot to put that the tempature is normal half way up. heater blowes
out hot at normal operating temp

 

This morning I decided to look for some new tires.
My VX takes P165/70R13 tires, so I hit the Tire
America site to see what was available. Several hours
later, it seems that almost nothing is available.

I love my econobox, & want to keep my 13" wheels,
so whats the best option for someone who drives
70 miles a day & 55 MPH?

My preferences are: Economy, good traction, &
comfort.

 

www.tirerack.com has some Yokohama's for $49 per tire. That's the ONLY tire
that came up when I put in your size.

 

The problem with older cars is that there are too many things that COULD
be worn out or not operating properly to cause the symptoms you
describe. Timing is not one of them.

My 89 accord uses 13's.. I put a new set on about 3-4 months ago.
The are kuumo's <sp>???.. So far they seem ok. Under 200 a set
including the balancing, etc.. As far as the rich running, the car
needs a total checkout. There are many things that could cause
that.

Thanks to both who replied. Still a fair amount of tread left, but
I'd like to be ready when the time comes for new tires.

Now, does anyone have an extra VX wheel they'd like to part with.
I need the original lightweight wheel to replace the donut.
