I'm inclined to suspect the EGR valve but occasionally, under light throttle (usually as I'm easing my foot on from no throttle), I get a "misfire" and then car accelerates as normal. I usually cover 90 miles a day and some days I don't experience it at all and sometimes a few times over the day. Never experienced it with enough throttle to turn out the Eco lights.

I know misfires don't apply to diesels but that's the best way I can explain it


EGR valve or is this something someone else has experienced they can shed some light on?

Yep it's a flutter rather than a misfire, and it's your EGR valve or IMRC solenoid (part of the EGR loop).

This is the first thing our customers report is solved when we map them out.

seems to be coming up more and more!

It's been coming up for ages on the accord forum but I think it's probably because the accord has had the ICTDI lump since 2004 so those cars have done a few miles now.. It's normally just down to these cars not been driven properly i.e. just short start stop journeys or low revs without a proper 'tune up - italian stylee' every once in a while.

 

[coste1l]

lol hopefully my regular "tune ups" will prevent this

 

[F6HAD]

Yeah I think you'll need a turbo and a good few sets of clutches, tyres and brakes before you need a new EGR valve :lol:

 

[coste1l]

:rofl: more than likely!

What are the consequences of disabling the EGR? Surely they are fitted for good reason? I ask as I also suffer from this problem.

to meet emission targets engines run better without them!

Thanks. How likely is it to affect the emissions test on the MOT?

 

[coste1l]

mot wont be an issue

Thanks guys. As long as it's just EGR.

I've only covered 1000 miles in it since I've had it a couple of weeks ago and no idea how it was driven by previous owner.

I do all A and B roads with a few miles of town each day but it spends most of it's time under 2000rpm. I'll take it for a run on the weekend

How much to disable EGR by the way? Not really interested in a full remap as my wallet is attached to my clutch.

 

[F6HAD]

PM'd u buddy.

Well managed to take a graph of EGR Commanded and EGR Error this afternoon.

Despite the EGR command not moving much away from 30% for the most part, the error seems quite jittery. As much as -100% out very briefly in places. Took these readings every 2 seconds. Orange line is the error and blue is commanded value.

What a great idea EGRs are

 

[F6HAD]

I think we've already PM'd each other mate. you know where I am

Yeah I expect you'll see it sooner or later

 

[-mike-]

Sorry to bump an old thread mate, but what did you use to log EGR commanded vs error? I need something to take to Honda so I don't get stung for no fault found or similar!
