colo, sounds very much like the symptoms of the EGR valve problem I was having before it was replaced. My Pilot didn't display the hesitation problem until it got really bad towards the end before the car threw up a code. Before that, the engine would vibrate or shake badly around 45mph-50mph.

Hopefully, your car will throw up a code real soon, so you won't have to experience that BS too much longer. When my Pilot was hesitating at those relatively lower speeds, the worst was when the third gear would eventually engage in a very harsh and rude manner. It was enough to jar your bones. It sucked big time.

When my Pilot finally coughted up the error code, the Check Engine and the VTM-4 light came on. Then once you pull over and shut the engine off and start it up again, only the Check Engine light will remain on.

But there will be no error code for the dealer to obtain from the car/ECU if the lights don't come on, AFAIK.

 

Thank you Riprock I'm still driving until the check engine show up thank you again I let you know the out come

 

colo, one thing I would suggest though is that, if your car consistently exhibits the vibrating/shaking/hesitation symptoms, you should take it to the dealer and have a tech go for a ride with you. If the car's behaving like that, you don't need an error code to show what's wrong with the car. The techs can see the car shaking and hesitating for themselves. Good luck!

 

Thank you Riprock I'm still driving until the check engine show up thank you again I let you know the out come

Don't wait until the engine light shows up. Have it check right away. RipRockwas an expert on this (hesitation & vibration). He endured almost a year of what you are experiencing right now before his pilot's engine light appeared and the culprit was the EGR.

Thanks guys I will.

Tomorrow I’m gong to the dealer let see what happen.

 

Ok RipRock thanks for you help the problem is gone the service advisor took note of what you wrote and they change the EGR valve problem solve I'm loving my Honda again.

Now I will install the fog light and trailer hitch that I have with me waiting for the 05 now I'm going to keep my 03

thanks again this site rocks:29: :29: :29: :29: :29:

I'm glad your Pilot is back in good working order again!!! Did they clean the EGR port and it's surroundings? If I remember it correctly, RipRock's Pilot, the dealer didn't clean the EGR port before installing the new EGR valve and he had to do it himself afterwards.

BTW, looking forward to the pictures of your installation of fog light and trailer hitch.

My guess would be that they did. That's what I'd bet on. It was just my bum luck that I ended up with the technician who forgot or neglected to do it.

 

This is timely. Two weeks ago my wife had the check engine light and VTM-4 light come on . She said the vehicle was driving fine. We were at the cottage near Midland so I took the Pilot in to the local dealer in Midland. They got a p1491 code error but said it was ok and reset it. The light hasn't come on since.
Yesterday I was driving the Pilot and it started to do the herky jerky while driving with the engine turning at @ 1500 rpm. I dropped by the dealer today in Whitby and took the service rep for a drive. He agreed that the herky jerky was definitely evident. I'm taking it in tomorrow and I shall print of a copy of this thread for reference.
Thanks for the info.

I think this EGR problem is a by-product of sulfur and MMT in the gas.

 

is this a really noticeable jerk, or more like a small buh-buh-buh kind of jerking....I think I'm feeling this now, with a bit of a rough idle...EGR? I'm going to have her checked, it's starting to weird me out, especially hearing the EGR horror stories.
Thanks for bringing this up.

Mine started out as you describe it , and it was intermittent as well. When my Pilot first started doing it the hesitation or jerking was so mild that I thought I was imagining it. Once I clued in to the rpms and road speed where the problem occurred if I feathered the throttle and held the rpms at @ 1500 I could make it do it all the time. You can get the whole vehicle vibrating. That "skill" came in handy when I was demonstrating it to the service rep today. Others, such as RipRock have indicated that the jerking can get harsher as the problem gets worse.

 

Ugh. I was afraid someone would confirm my fears. Thanks, scoobs, I'll try out your technique.
Should I ask them to see if it's throwing a code first? It's had a bit of a rough idle from day one, but now i'm feeling it on the road. I'd hate for it to turn into something worse. I too thought I was just imagining it, or just being paranoid.
Thanks so much. I'm calling the dealership today.

 

I had the Pilot in today and the dealer agrees that it is probably the EGR that is causing the problem. Unfortunately the new EGR won't be in until tomorrow so it's in to the dealer again. I shall post after the final repair. The dealer said they called Honda's tech line and Honda Canada advised that they are now starting to get enough of these EGR complaints that they are issuing a bulletin to the dealers ( for all I know thet already have ). My service rep said he thinks the EGR was defective from the "get go" and that the problem is not caused by bad gas.

 

The EGR was replaced today. The Pilot now runs fine and there is no hesitation or jerking at 1500 RPM, it's gone.

 

Just notice today

Hi all,

Me, too. After transmission recalled today is my first time taking kids to the lakes, Mannnnnn the up/down hill and the hesitation and vibration is really piss me off. usually between 18MPH - 60MPH I can feel the hesitation / vibrate.

I'll call the Dealer Monday.

mmmmhmhrrrggg

My Pilot ('03 EX w/26k) just began to exhibit this problem!

Very repeatable at pretty much any speed at ~1500rpm. I'll keep you'all posted. I have a pending appointment for strut-tower and spring replacement. Starting to worry about not working out all the bugs during the warranty period. (And there's been lots of bugs) But I still love my '03 pilot... I think.

Just curious, would a bad EGR affect gas mileage?

Just curious part 2, what does EGR stand for?

Just curious part 2, what does EGR stand for?

Exhaust Gas Recirculation.

 

Exhaust Gas Recirculation.

Thanks! I guess there's nothing wrong with the exhaust gas recirculation, then. At least based on a recent deep sea fishing trip with some buddies... especially after that all-you-can-eat buffet. :16: :runaway:

 

I have a 2004 Pilot with 6800 miles on it and seem to be having a similar problem.

The engine is running very strangely. When I turn the vehicle on, the “Malfunction Indicator Light” (the one that looks like an engine) comes on immediately. Then when driving, the 4WD system kicks on and the VTM-4 light goes on. Also, when driving, it will downshift very roughly. From a complete stop, I can let go of the brake and the vehicle will slowly accelerate and reach between 25 and 30 MPH (without pressing the accelerator). Then when I stop the vehicle and place it in park, the idle jumps between 1000 and 2500 rpms with the engine revving by itself.

It's going into the shop tomorrow, but I'm wondering if you think this would be caused by the EGR value, too?

Thanks.

EGR valve fixed my problem....

Hopefully I'm good for a while.
