    Hi,

    Firstly - sorry if this is a common problem and I've missed a blatant thread on it....

    I have a 05 Accord tourer I-CTDI 2.2, 90,000, reg oil changes, reg service.

    Cold engine, foot down, power cut at high rev around 2.5k+ (lunging me forward), this has happened before but a change up in gear usually solves. This time was different, changed up to 3rd and experienced a juddering (like a bunny hop), then car stalled. Loss of power steering as well. Engine would turn over but not start for around 2 mins - then eventually started. EM light came on and remained for the next hour or two, then disappeared.

    Has anyone experienced anything similar?

    Trying to remember - was serviced last august and we can't remember if we changed it then! Is there a way to diagnose if this is the cause?

    Easiest way is to just change it. But it has to be a genuine Honda item. Non genuine ones quickly lead to problems.

    There are comprehensive instructions on the site on how to change.

    thanks - changing it now. Hopefully it will yield some good results! 250 miles to do tomorrow evening!

    Was the old fuel filter made by Bosch, part number ending in 442? If not, then that'll probably be the reason... these engines are really very fussy when it comes to fuel filters.

    Have you got access to an OBD2 code reader? Diagnostic Trouble Codes P1065 and/or P0087 are a good indicator of a restricted fuel filter, as is the glowplug warning light coming on (which you didn't mention).

    Had the fuel filter changed, not by myself - don't know if the old part was bosch as I wasn't around when it was done. However on speaking to the mechanics, they haven't experienced problems with non-honda parts.

    This weekend, at the end of a long journey, the engine went into limp - no power above 2k RPM and glow plug light flashing. Given that the replacement fuel filter was literally only 300 miles old, could it still be this?

    additional - sometimes under acceleration, the throttle blips - the severity of which depends on where you are in the rev range, the higher the rev, the harder the throttle blip feels.

    If you know anyone with an OCBII code reader that would be your best bet for diagnosing. You can get cheapy ones on ebay that are used in conjunction with free software on a laptop. They are about £15 and up.

    Thanks - I guess that'll be my next port of call. Does anyone have one in/around bedford?

    there is a whole topic on OBDII scanner reviews if you search. Plenty of options.. starting as low as £5

    Can you confirm that the new fuel filter was definitely made by Bosch? It's usually easy to see.

    I don't care what those mechanics said, the single biggest cause of low fuel pressure problems on these engines is due to having a non-OEM fuel filter. The glow plug indicator coming on is (strangely) an indication that the fuel rail pressure is low.

    Hi, sorry for late input on this.

    I had this happen a couple of times, if I revved the engine up to the red line while accelerating it would just die and the MIL light came on (can't remember the code, sorry). But at the same time I was having the error code P2004 referring to the Frequency Solenoid not working correctly, this was an intermittent problem so didn't change the part straight away, but when I replaced it the P2004 code has never come back and I have never had this cut out problem again either.

    Link to my other thread - P2004 - Frequency Solenoid Valve (Engine & Gearbox - )

    Update: have been out and about this morning - hard acceleration with foot flat down, high rev ranges at various speeds, no issues. Love these intermittent problems! Thanks to all for your help so far. I have arranged a trip to get the codes read on Thursday so hopefully all will be revealed (if anything is left on the computer) then.

    Thanks - arranging a trip to a OBD2 scanner on Thursday.

    Thanks a bunch for this - we'll see on Thursday if this is the case. With mine the glow plug light flashed.

    I don't think it is a bosch (but can't be certain) - once we've had a read of the codes on Thursday this may be an avenue to try. This would be the first time ever I've heard of non-OEM parts causing issues straight away - nipped in to Stratstone Honda this morning and the mechanics there couldn't confirm what you're saying. It's difficult for people like me (non-experts) when I'm being told two conflicting things!

    If you don't believe me, then search this forum, the TypeAccord forum and/or the Civinfo forum to find literally scores of examples of where I-CTDI owners on those forums have had problems after not using the correct fuel filter - use the search terms 'P1065' and/or 'P0087'. Yes, your current problem may not be the fuel filter (although the glowplug warning light is a pointer to this) but having a non-OEM fuel filter is a problem waiting to happen, even if it seems to be OK now.

    If you don't currently have the engine warning light (MIL) on, then using an OBD2 reader is a waste of time, as you'll only find stored historic codes that will cause confusion.

    I can concur with what @Zebster is saying 100% correct.

    I'm in a rush but will quickly say that what most people that don't frequent forums miss is the point that forums such as ours (and all the others such as the ones @Zebster has mentioned) accumulate a lot knowledge, an immense amount of knowledge. This accumulated knowledge can easily outway even a person whose day job it is to work on cars.

    Trust us on this one my friend !

    Completely agree with both speedy and zeb. This forum has some very knowledgable people including Honda trained staff and mechanics.

    Most of the information on here is absolute gold and in certain arwas; outweighs garages who don't specialise in hondas.

    As a CTDi owner myself, they are incredibly fussy and need a bit of babying. Regular servicing using OEM parts is vital. At 90k mileage, your EGR could be dirty which can also lead to hesitation

    Re post #1
    Have you considered that it may be the drive by wire throttle sensors? I had the same symptomatic behaviour for 4 weeks and then limp mode came in 3 times, throttle sensors in engine and on pedal wee replaced - no issues since then.

    I haven't considered that no - did you get any codes come up relating to the problem? Fuel filter has been changed but it's still happening and same codes appear. Mechanic is now thinking it may be fuel rail pressure sensor, but I will let him know your problem/solution and we'll go from there! Thanks!
