#4887 of 5868 Mysterious hesitation when it snows 06 Accord
Nov 18, 2009 (9:33 pm)
Need help with a puzzling problem on my 2006 Accord – Maybe the car experts might have some solutions:
In cold weather, when it is actively snowing, the car will jerk or hesitate when accelerating. It feels like someone applied the brakes for an instant. This happens once in a while, say from 30 seconds to 30 minutes apart, and only when it is snowing. I have no problem in the summer even when it is raining.
The car will lurch in any gear when accelerating but does not jerk when coasting. I am not spinning the tires or losing traction, it can happen on level dry ground (no snow accumulation). The window defrost is off (e.g. heat to feet only, so it is not the AC), rear defog off. The engine could be hot or cold, it does not make any difference.
There is no engine trouble light, no flash of any of the dashboard lights, and no codes, Honda replaced the ABS brake modulator but that did not make any difference. I asked the dealership to check with Honda engineering but they did not have any ideas.
The car is a 5 speed manual so it is not a poorly shifting automatic transmission.
Specs: Accord SE, 4 cyl, manual, no modifications. This model does not have traction control.
This might be a clue or a completely different issue – any time of the year, the car has an uneven acceleration when the engine is cold. It goes away when the engine warms up.

This is only a guess, but if you have "drive-by-wire", have you ever had the throttle-body cleaned? Was the EGR system checked, by the dealership? That's all this shade-tree mechanic can think of at the moment. Good luck

had the 2005 in for an oil change today, so I complained about the squeaky clutch linkage again (the clutch master cylinder was replaced a couple of years ago). Service dude disappeared into the footwell with a can of spray lube, and seems to have eliminated the noise.
so, no need to haggle with them about another new MS (since I am out of warranty now), and the massively annoyning (but functionally irrelevant!) noise is gone.
If it comes back soon, I will request that they dig deeper int the problem. Or just buy myself a spray can!

Wasn't there a tech report from Honda that said the Master Cylinder should be replaced because of a squeak? I replaced mine for this reason a couple of years ago. Although the new MC took care of the squeak, it returned months after I changed it out.
There was no way I wanted to replace that thing again so I squirted some WD40 into the cylinder (where the plunger of the clutch linkage pushes into the MC) of the MC and that took care of it, no more squeaking. It's been about a year now and still no squeaking.

I had a new MC too about 2 years ago. I believe what the service advisor (never even made it back into the shop, this was the guy writing me up) was the same basic thing, he lubed the shaft that went into the MC. If it starts squeaking again, I wil just get it all lubed up.

Another guess is the accelerator sensor/driver unit if
your car has drive-by-wire.
#4893 of 5868 upgrade du jour

swung by wally world today to get anew everstart battery in the Accord (it failed the load test yesterday when I had the oil change). Not tremendously more powerful than OEM (not sure why they don't make a big honking Maxx version for this car), but certainly cranks better now. And I can reasonably expect it to start after sitting outside all day in the cold (it was a crapshoot last winter!)
This would have been the 5th winter on the original, and no way I was chancing that.
#4894 of 5868 Need some input. AC, Heat and front defroster
Nov 21, 2009 (11:54 pm)
I have a 03 Honda Accord EX V6 coupe. Suddenly, the A/C, Heater and defroster stopped working. Since I am having GREAT difficulties getting Steven creek Honda in San Jose to address the issue (dealerships are crooks). They stated it was a relay, but won't tell me which one. I am lucky I love working on cars and will just fix it myself..
My question: Is it a relay under the hood or the blower motor relay???? Both are easy to change. I need to get it working before Wed.... leaving for Thanksgiving and not really looking to the trip without defrosters and heat.
Thanks.... eager to know more.

I know it's hard to believe, but you may have a weak battery, causing communication errors with the MICU. Try disconnecting the battery, and retry the A/C. Hope you have the radio code.

Sounds like the blow motor relay.
You can do the continuity test between the terminals.
Or you can swap with the rear window defrost relay and see if
the problem goes away. I think they are the same relays.
