If the car has been sitting overnight or for a long period, the gas pedal sticks in the up position and you have to push it kinda hard to snap it loose, then its usually OK. Anybody else encounter this? Possible cause/fix?

1999 Accord 4-Door EX 2.3 I4

 

One of two things... Either your throttle cable is lacking lubrication or your TB butterfly plate is sticking. I'm gonna guess number two. Yank your initake tubing off and take a gander and see if any "gunk" has built up on the inner walls of the TB. You'll most likely find some. Carefully unplug the TP sensor and remove the four nuts/bolts. There's a gasket you will need to purchase as well from Honda... it's $15 if you're getting totally ripped off. Be careful not to drop your TB as that TP sensor is a bit expensive to replace. Buy yourself some carb cleaner and hose down the inside of the TB (with the carb cleaner and not your garden hose). You should be able to wipe away the residue with a soft & clean rag. Make sure to scrape off the residual gasket material left on the IM and the back side of the TB. Installation is the reverse of removal. While you are at it you might want to switch to synthetic oil as this will not cause buildup in the motor and you may want to check your PCV valve to make sure it hasn't clogged. Happy cleaning! By the way this isn't atypical in Honda's over 7 years old.

 

put some oil on pedal and it might help =p

 

there is a bulletin on this ,...... remove and clean the throttle body with carb cleaner

I don't mean to bitch here guys but WTF did I waste my time writing this for if everyone is simply going to follow up behind me and type

Post the link to the bulletin or don't bother posting. Dammit man... Read what I wrote already.

 

If someone could link me to this article I'd be much abliged. Does this article include a how-to for removing the T.B. and reinstalling for us fuel-injected ignorant folks? Or is it literally 4 nuts/bolts and its off?

 

I tried pulling it up a couple of different ways in the seach listing and found only stuff relating to adjusting the stop screw... which you need not worry about.

It literally is two nuts and two bolts (diagonal from eachother) after yanking the intake tubing. This really is a DIY job. You'll need:

*Rachet (1/4" or 3/8" drive) with 3" extension and 10mm/12mm/14mm sockets
*Two screwdrivers (#2 Phillips) and a flathead.
*New Honda TB gasket
*Gasket scraper (or a putty knife)
*Carb cleaner
*Soft clean rag

If you've got all that then you can do it! I don't remember the exact sizes so I figure send you in with the artillary and you won't be unarmed if ya know what I mean. These are all the tools you will need from start to finish on this project... Good luck and if you think you will have any trouble figuring it out buy a $20 Haynes manual at the auto parts store; this can be a very useful tool for a number of DIY tasks.

 

From another thread:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by mwkirchner &raquo;</TD></TR><TR><TD CLASS="quote">Honda has issued a bulletin discussing this. It is bulletin #01-004

Here are some excerpts from it:

SYMPTOM

When the engine is first started after the vehicle has sat overnight, customers may “feel" the release of the throttle plate through the accelerator pedal. Some describe it as a one-time "pop” sensation.

Customers may have trouble explaining this phenomenon because:

• They can’t repeat it because it only happens one time, when the engine is cold.
• The accelerator pedal works normally at all other times.
• There are no other symptoms.
• It may be intermittent, happening only during cooler weather.

PROBABLE CAUSE

The symptom is caused by normal buildup of contaminants in the throttle bore, combined with expansion and contraction of the throttle body.

You don't necessarily need to take the TB off. I never have.

Not to mention this thread is already in the Accord FAQ:

Calm down. This question gets answered nearly every week already. Everything a person needs to know can be found in a quick search. And the Accord FAQ has the link showing how to clean the throttle body.

The decision is yours to make Ciffsta but I personally would remove the TB for one simple reason... The residue built up on your TB is a product of oil residue and air intake debris that bypassed your filter. You will be using carb cleaner to breakdown and remove this oil residue and debris. This debris will then end up in your oil system eventually not to mention the carb cleaner (which we used to break down the byproduct of oil) in your oil pan. Is this what you really want mixed in the motor oil that cools the bottom end of your engine and lubricates the head? I personally would not... there are easy ways to do things and there are hard ways to do things but there are usually very few right ways.

PS - Sorry... didn't mean to trip.

 

there is a tsb on that and the dealer can make the repairs if you are uncomfortable with doing so. Use a heavy duty Intake cleaner and make sure that your air filter is properly seated and sealed.

Posting a link to information that might be copyrighted is a violation of the forum rules. I've been busted for that in the past week.
Don't shoot the messenger LOL
