    Hello i hardly post in this forum because I've never really needed to, but the time has come where i believe i have to.
    I own a Honda Accord I-CDTI 2005, i have an intermittent problem. The car stops accelerating from 4th and 5th gear, even when the foot is down it feels like its losing speed. Also sometimes it struggles to accelerate from stand still, pretty dangerous living in Milton Keynes with the roundabouts. Sometimes it blips from 800-900rpm when this is happening. It is intermittent as it drives fine sometimes. I must say that when i put my foot down sometimes i get a quick drop in acceleration like its starved of fuel or air for a second then goes back to normal.
    What i have had done already is:
    Fuel filter
    New TPS sensor
    Throttle body cleaned thoroughly
    Intake manifold cleaned even though it was not that dirty.
    I think thats all that has been done.
    Can anybody else think on anything it could be from past experience?
    Thank you in advance.

    I have fitted a new fuel filter from honda, after bleeding the fuel system it started and run OK. Now it takes ages to get from 1k-2k RPM. Turbo kicks in well but it feels that I'm down a lot of torque. I've disconnected the battery for while to see if does anything.

    You were right to change the fuel filter, even if it didn't help. That aftermarket one would probably have caused a problem for you one day.

    You've not mentioned any warning lights, so I'm assuming there aren't any?

    Have you checked out the EGR valve? The pipework doesn't have to be cleaned out, but the valve needs to be clean enough to close fully and without any sticking. Your pre-facelift model has the superior electrically-operated valve so is a little more reliable than the later vacuum-operated nightmare, nevertheless they can play up. If you do remove it to have a look, then it's a good idea to test how well it's working by applying voltage to the pins, as shown here...

    OK thanks I'll take a look but in all honesty I do not think it's the EGR valve.

    Why not? If it's sticking open then the ingested exhaust will be displacing the fresh, oxygen-laden air into the cylinders and causing running problems.

    Otherwise, I suggest you find someone with a Honda Diagnostic System (or equivalent target-setting interactive diagnostic system) and have them test each engine sub-system. That should at least pinpoint the problem area.

    Do make sure you test it... Cleaning does not cure all problems!

    They cost a fortune. I'd clean it and test it as shown in that YT clip before considering replacement, which would probably mean getting a secondhand one.... Lots of old 7th Generation diesels get scrapped because their timing chains snap, but they probably have working EGR valves.

    I'm still waiting for an EGR valve to be delivered. I'll update once it's fitted. I hope it cures it.

    You bought one! Did you prove that the old one was faulty? If so, then no need for hope!

    If you've bought a secondhand one then I strongly suggest that you test it before fitting it.

    I've put cleaner in and it's still the same. Drivable though as it's slightly faster from 1-2k RPM. It's fine after 2k. Yea I'll get it tested before I fit it. Thanks
