So I ran into a slight problem last week. I started my insight and the check engine light came on. Strange, Just had the ECM recall 3300 miles ago. I called the dealership on tuesday. Told them what happened that morning, cel, and it was running rough when at idle. They told me to stop by. They looked at the freeze frame data and reset the computer. The error registerd (undefined) P-9999. So they told me they wanted it longer, but wanted to see if I could recreate the cel, so I should drive it for 2 more days after the reset. Took it back thursday, still running rough and no cel. They had it until saturday and could not figure it out. They said they tried calling the Honda Tech line, but were not getting through.

My question is; Has anyone else seen anything like this? My dealership is not sure what is going on. I have the car back now, and they are going to attempt to contact the honda tech line. But, I figured I would as here to see if anyone has had this problem.

Much appreciation for your thoughts.

EGR Valve... I am replacing mine today. Honda engineers said that is the problem, very easy fix! $130 from Honda if you need to purchase it from Honda, part stores do not carry them. There are 3 bolts holding it on with 1 wire plug. Located right in front of engine, if facing the windshield located about 6 inches from the hood latch slightly to the right about 4 inches. Just pull the cover off the top of the valcve cover, 2 bolts and the front pops off of rubber gromets.

Let me know if you do end up getting your replaced and that it DOES fix the problem. Be sure to check with your dealer first though.

EGR Valve?

EGR Valve? I'm considering bringing mine to Honda because it tends to idle rougher than I thought. Can anybody verify this is normal:

If I put the car in Drive and let it coast slowly (It's CVT/Automatic) w/o applying any gas, the engine will move the car slowly but it sounds rough, like it wants to cut out. Sometimes I fear it will. Other times at very low rpm's while driving or something it sounds as if the motor wants to cut out for no reason.

Other thing I've noticed is whenever I'm braking to slow the car down gradually, like coming up to a turn, I'll keep the same pressure on the brake pedal and it'll normally decelerate at a constant speed, but now about halfway into deceleration it'll jerk back more as if I'd pushed on the brake harder but didn't. It could be the charging system in the brakes that caused this but I don't recall it doing this before. But it's annoying to use the brakes to slow down and in the middle of slowing it feels as if I'd just hit the brakes harder.

Whenever I let it idle and move around the parking lot or whatever (above/1st problem) it FEELS like the brake is engaged, like it's being choked somehow from moving the speed it normally should. I don't know what to make of it. Could it be the EGR valve? I'm not sure if it's normal as I've logged less than 500 miles on this car, but I was going to bring it into a dealership and have a detailed analysis done it, make sure it's tuned up and running right and that the brakes are in perfect running order.

Ohh well, if something did break down the line, I have extended warranty, but I'd like to nip any problem in the bud, before it becomes a bigger nuisance. I don't want an el-cheapo rental while they fix my car.

I am taking it in today, I will mention it. Thanks. I will keep you posted.

not the EGR. Honda said it was a dirty throttle body, so they cleaned it out again. Keep in mind, I just had it done less than 4,000 miles ago. I still think it is rough. Rouger than my wife's civic at idle.

the saga continues

OK, so it was really bad yesterday on the way home from work. I called the dealership and told them I was coming in. THey had one of their seinor techs look at it. He agreed that it was running very rough. They are going to call Honda Tech line for advise on where to go from here. I will hear back today about noon. I will post when I hear something. Is anyone else having this problem or has anyone had this problem?

 

[Allnighte]

can you define your rough idle a little more?

i notice when the car stops, and puts into park, the revs will drop a bit below 1000, and it gets kinda rough, but then they go back up to around 1000. as if there's a sensor preventing the shaking.

the only time i've had wierd idling experiences was through a drive through (auto-stop wasn't engaging, i was idling) and i turned on the A/C. the revs would drop down to 500 (which makes very rough shaking), and make this really throaty-empty-can-idle noise, but then would go back up to 1000, then back down to 500. and this would repeat until i turned off the A/C.
how are your RPM's when it is idling rough?

 

[uvman]

sure I can explain more.

Warm car, 6 bars on temp indicator. running about 1000 rpm steady in neutral. No AC, and it is too cold to autostop. The engine shakes so hard, I can feel it in my body when I am sitting at a light with the car on.

I opened the hood, and it is almost voilent, that is how much it shakes.

 

[Allnighte]

does it shake really bad when it's warm outside?

 

[uvman]

yes

Shaking Car

If the idle is that bad something could be wrong with the IMA. One of the jobs of the IMA is to dampen out the 3 cylinder Engine vibrations. Mine is much smoother than my Civic. Have fun, Rick

Interesting, Talked to Honda again today. Tech line wants about 30 minutes data capture to analize. I am taking it in on Thursday night. Local Honda dealership/service will capture that data and send it to honda corp, tech line. They will advise on what to do.

As far as the IMA dampening the engine, I know it is supposed to do that, however, the IMA seems to be working ok under demand. That is not to say something is not wrong. Maybe a vibration sensor that allows the IMA to make the adjustment for smooth running. I like that idea though. I will bring that up thursday with the tech when I drop off the car. Thanks for your input, I willkeep you posted.

Idle

Perhaps the IMA pulses are out of phase thus reinforcing the rough idle. One way to check is to disable the IMA and then see if it idles any better. If it is better then the IMA was out of phase, if its the same then the IMA is not dampening the engine, and if it is worse stand back or turn it off. Hope the problem gets solved. Have fun, Rick

Update

Honda captured some data during a rough idle, and sent it to Honda Tech Assistance for analysis. They had some ideas, and saw something that they did not like. They told my dealership what they needed to do next. It will be in mid next week again. I will keep everyone posted. I only spoke to the service attendant, not the mechanic, so he could could not give me any details about what they were doing or what Tech assist said. I will talk to the mechanic when I take it in and get the full technical scoop on what honda said and what was done so I can post it. That way if anyone else has the same issue, it will be well documented here and you will not have to research as much.

idle relearn

Honda did a idle relearn procedure. The shake is a little better but not 100%. I am going to drive on it for a few days and see how it feels.

 

[dtlee]

What was the resolution to this ROUGH IDLE problem? And how do you perform an idle re-learn? My car is idling rougher than my friend's CVT but still smoother than my CRX, M3 or 911 did.
