Accord Coupe throttle hesitation

02 Accord Coupe V6 automatic. When cruising at a steady speed and I push the
gas pedal, there is a slight hesitation. Not quite a bog, but it just seems to
hesitate, then starts to build power. Power is good, no miss. Just slow
response to throttle. If I nail the throttle, it does fine. I'm talking about
just feeding in a little throttle, not WFO. Dealer said he can't find anything
wrong and admits he can't feel the hesitation. I've driven enough vehicles to
know this is definitely a hesitation. Is this a normal trait for this car?

 

Likely the way the ECU is programmed for fuel economy puposes.

car?

 

That's what I figured and probably the reason the dealer says there is nothing
wrong. To beat it all, fuel economy isn't that impressive. 200 hp with the
same fuel economy as a 400 hp Z06 Corvette.
Is it possible to reprogram the Honda ECM?

 

================

Without knowing a few more details, I'd guess that the timing belt is
off by one tooth. The ignition timing may look correct, but the cam will
be out of time, causing hesitation, and poor mileage.

I'm beginning to think it's just the nature of the beast.
I've noticed the same thing in my '03 as well.

It really sucks. Otherwise, I love the car. It's my first Honda car after
many Honda motorcycles. But, it will probably be my last as it is very
annoying. I like to be able to just ease into the throttle sometimes but you
have to jump on it to get any response.
I'll check on the timing belt situation. Or, have the dealer do it as that
would be a warranty issue.

 

Bring it back to Honda and tell them you're not happy. Have them re-set the
ECM, and make sure all the TSBs are taken care of for your car!
