Hesitation Blues, Part II

I have a 1992 four-door Acoord EX with AT and 166,000 miles.

I sometimes get a horrible hesitation when I either take-off from a dead stop
or when I speed-up from, say, 1,000 RPMs. Not only does the engine not rev, but
also it seems like something is physically preventing the gas pedal from
depressing.

Starting, cruising and turning off the engine are all normal, as is fuel
mileage.

TIA,

Jimbo

if it feels like that, it may indeed be a throttle problem. inspect
both the pedal end & throttle body ends of the cable for free movement &
fraying. if the cable has frayed and gets jammed, you can have a
throttle stuck open. could ruin your whole afternoon.

 

your throttle body is all gummed up


remove hose to throttle body

spray some fuel ingector cleaner ( not gum out may harm sensors ) into throttle body

clean inside butterfly plate with tooth brush + rag

once clean and shinny

jam a screw driver to hold throttle body butterfly plate open

let air dry for a few hours

do not start immediately let dry 100% you do not want the chemicals on the sensors




good luck

Thank you for your time and advice. I went to Advance Auto today and picked up
some throttle body cleaner. Before I used it I discovered that the throttle
cable on the side away from the gas pedal was non retracting and occasionally
stuck coming out. this cable runs from the side of the battery (where it has
like rubber bellows shrouding it) to the throttle. It is not always moving
freely. Otherwise, the throttle itself seemed to be OK.

How do I lubricate this cable and is there some type of spring which make it
return and takes up the slack?

As always, thanks in advance,

Jimbo

motorcycle shops have a cable lube device for sale that might just work.

its a piece of billet aluminum that has a rubber part. the whole thing
slips over the end of the cable, and you attach the spray tube/nozzle
thingie from a can of cable lube to it.

it forces the lube (cable lube/wd40/whatever) into the sheath and
through until it comes out the other side. when the inside of your car
smells like wd40, its done!

or take the cable off completely, and hold it by one end while you
dribble lube down the cable until it comes out the other side.

or replace the cable....

on my motorcycles clutch cable, i always went with option #2.

cept for the first time when i didnt lube it at all and it rusted
through and broke. then option #3 was the only option.

from then on, every couple years id do option #2

 

i'm a great fan of wd40 for freeing up siezed parts, but not as a
lubricant. it dries off, and then you're into metal-to-metal contact.

the honda throttle cables have a plastic liner which is supposed to be
lubed for life. if it's gummed up because the boot at the end was left
off, by all means, try freeing it up, cleaning & relubeing with a light
silicone [so as to not dissolve the plastic liner]. if the liner's
damaged, it won't run smooth & could get jammed, or worse, allow the
cable to fray. in this case, i _strongly_ recommend replacement. when
i was a kid, my dad had a throttle cable sieze full open because of
fraying. it was "interesting" for a moment or two.
