Honda Car Forum

My accord always hesitates for a moment (less than a second) soon after I
first start driving it. I would say I drive maybe 1-2km and then the engine
for just a moment appears to almost stall then runs perfectly. This only
happens when the car has sat for a long enough period to cool off fully. It
has no other problems and it works fine if I were to be on a lengthy drive
say 500km or more, just that initial "almost stall" and then recovery.

By the way its a 5 speed 4 cylinder, around 90000km. Anyone have any ideas?

You should have your fuel filter replaced during your next scheduled oil change.
Also, buy a can or bottle of a chemical that you pour into a full tank of
gas that helps clean the fuel injection system.
Also, incorrect timing can cause this problem. If the above suggestions
don't solve the problem try resetting the timing, changing the spark plugs
and checking for any air leaks.

Why?

How would any of these suggestions correct the problem his car is
demonstrating?

Per Haynes: "Engine stumbles on accelleration":
spark plugs fouled
Fuel Injection System faulty
Fue filter clogged
Incorrect ignitiion timing
intake manifold air leak

Didn't see any diagnostic guide in the factory service manual.

Thanks for the input everyone, I can try everything here but the timing.
It is almost due for a new timing belt anyhow, but I'll leave that job to
the experts.

That all implies a persistent condition, the OP reports one
nonrecurring event with each start.

I should have mentioned that I got the information in my post the same
place where you got the same information in your post.

Appears to be a great plan.

It should be mentioned that the OP did *not* describe an Engine which
Stumbles upon Acceleration...

What is your solution for the problem? As most any mechanic will tell you,
the same factors that cause an engine to "stumble upon acceleration" can
also cause an engine to "hesitate". Obviously, just as doctors disagree on
solutions to a medical problem, I'm sure that mechanics disagree on
solutions to an engine related problem. It's a lot easier to criticize
those that provide advice than it is to provide advice.
