Honda Car Forum

Good Morning all
Hope you can help or at least point me in the right direction. I have
a 99 honda Accord, 4cyl VTEC.
car starts great, runs well, idles fine.... just no power, acually
midrange. I try to get on the highway... it just cant get out of its
own way. but once i get up to 65-70...it will run fine, then hit a
small grade... it just can't keep up.No check engine lite, so does this
mean not an emmissions problem? or a non sensor problem?

I did try injector cleanner, and better gas... no differance, changed
air filter, still the same.The car has apox 131K miles

thanks for your help
Jeff

when was the timing belt changed? if it wasn't tensioned correctly it's
skipped a tooth.

When was a full tuneup (air filter, fuel filter, ignition
wires, plugs, distributor cap and rotor replaced, timing
checked) last done? Were OEM parts used for these?

While the fuel filter is not commonly a problem, nonetheless
depending on your response to the above, I would suspect it
and replace it first.

Like you suspect, if the oxygen sensor is not working right,
you really should have a check engine light with a code
indicating the same for this model of car, plus other
symptoms.

....hate to say... have NOT had the belt replaced...yet. (on the list of
things to do)

tune up was done about 30k when i got the car, however I didnt replace
the wires.(OEM was NOT used) But i did use, I believe Sorenson parts. I
have NOT replaced the fuel filter, mainly because.. I dont know were it
is located.
I will do some parts replacing tonite fuel filter, wires,.. timming
belt over the weekend w/ waterpump.
I did think about the tune up, but it doesnt miss or sputter, so I
kinda ruled that out.Looks like i will start there and hopefully it
will run like a champ as it did before.

thanks again all

Jeff

I would do these, with the fuel filter, at the same time.
This may very well result in significant improvement
immediately.

FWIW, there are several free web sites, typically with
drawings, that might help you with locating this. Maybe
peruse the list at
http://home.earthlink.net/~honda.lioness/id9.html , for
starters.

If the timing belt is due, sure, get it done, because one
rolls the dice on destroying the engine with a failed TB
otherwise. But I doubt it's behind the problem you
described.

Another cause of loss of power that is often overlooked is a plugged
catalytic converter though in this case would be an early occurrence.

Well i looked up the fuel filter.... well its in the tank..
so im not sure if that will be the problem... basicaly a screen...

Oops. I was thinking of older Hondas, whose maintenance
schedules do specify fuel filter replacement every 60k miles
or so. Your 99 Accord's maintenance schedule has no such
specification. I recall the filter not being where it is (on
your Accord) for older Hondas, too. So, yes, I'd let this go
for now, and keep investigating the other possible causes.

i just picked up a set of new plug wires ( originals were still on)put
new set on....maybe a litte better but NOT THE PROBLEM. looked over
wires ,vacum hoses,...could it be a cat converter...
ok im throwing out a sugestion.. could i have a transmission problem
not letting it shift properly..

HERE IT IS.....Your catalytic convertor is clogged or collapesed. Have
someone hit the gas while you are at the tailpipe.....if not
strong.....there it is.
