Hi guys. I'm new on here so I hope you'll bear with me!

I'm having issues with acceleration on my Civic 2.2
Car runs just fine when cold, but when it warms up it bogs down/ sputters, mostly in 3rd and 4th gear.
Basically i accelerate normally, change gear and the car gets sluggish. It feels as though no power is getting through at all. If if take my foot off the pedal then re-apply, or give it the beans, it will work fine until i change gear again. I can hold the car in this state when it happens and it chugs as though power is going on - off - on - off.
It can be bad enough that i move forward in my seat, as though i was suddenly braking. I get no warning lights, haven't seen any smoke from exhaust. Local Honda dealer "can't replicate the problem" so I dont know what to do from here. Any ideas?

Sorry for the long post. Hope it all makes sense.

Hi welcome, if the fuel filter hasn't been done in some time, I'd suggest that first and make sure it's a genuine Honda item.

After that my money is on a sticking EGR valve or possibly sticking vanes in the turbo.

What mileage is the car on and what sort of journeys do you do?

If it's the EGR valve, we can disable it as part of a remap.

Thanks for the welcome.
Mileage is 77,000. Don't do enough long journeys for a diesel to be honest, so carbon build up in EGR might be likely, if thats what you're thinking.
Is there any way to test the turbo for malfunction? Can i get to the EGR to check that?
What effect does disabling the EGR have?

chucks the crap out of the back instead of forcing it through the engine! does the car get abused ocassionally? if youre doing short journeys and getting 50mpg it will be getting coked up. try some bg44k or whatever its called and give the car some welly

+1 on the bg244.

Italian tune time my friend
Take it down the country lanes and rag the arse off it (wide open throttle 2nd/3rd from 2000-4500rpm) for at least 30 minutes.
Lots of on off throttle bewteen 1500-3000rpm too as this is when the EGR shuts and closes.

1. Check oil and water levels beforehand.
2. Keep an eye for smoke.
3. Keep an eye on the water temp gauge.
4. Make sure the battery connections are tight and charge good.

They should be fine if it just needs a clear out but if its something far more fundamental you dont want to be overcooking the engine.
Could be a fuel delivery issue...airlocks..clogged filter..knackered pump...failing injector.

Also make sure the boost pipes are clamped tight and the airpipe at the back of the airbox is tightly clamped.
Not unusual for this to be left loose after airbox removal.

Positive allround really, sharper throttle response, marginally improved economy and a cleaner breathing engine. And no effect on MOT either.

Thank you for your replies guys. I appreciate all your input.

Just a quick question mate,

I have put the bg244 in on monday since then I have driven very lightly, as I thought that it was better to drive uber economical until gauge reads half, refuel and then boot it.

Is this correct?

Or should I hammer the guts out of it?

Oh also when I floor it in 2nd and all the lights come on the rev limiter should I just keep my foot down for about 5 seconds or release?

 

[Relic]

Hammer the damn guts out of it after refuel
Its takes time to soak in evidently so the longer it soaks the better.
But you still have to shift it and the higher the temps and pressures the better.
However, higher temps also make it react quicker

5 seconds on the rev limter....:shock:... no matey.
Dont have to be that aggressive.
4500rpm and change gear is fine....the extra 300rpm wont make much difference for cleaning.

 

[coste1l]

make it 10

 

[griffian]

LOL!

Am I doing damage then by holding it in second at 4500rpm with on all lights on?

 

[Relic]

At 4500 no.
It has a rev limiter set at 4800rpm
If you just stick it in 2nd and keep your foot on the floor at 4800rpm while you watch TV...you aint going anywhere fast (ECU cuts fueling) and your engine will get out and kick you in the nuts

Like so....

 

[F6HAD]

That is brilliant :lol:

Good explanation mate, love it LMAO!!!!!!
