H E L P  I have had a remap stage one and egr blanked (thanks Farad) but engine still misfiring (if it was petrol i would suspect faulty leads/plugs ) but it has been in garage for a week now and has had injectors refurbished  fuel flow checked return fuel flow checked  but the dammed thing is still "missing" you can smell the unburnt fuel!! I pick it up tomorrow and will be getting a written report as to what has been done will post results when i get them.....any ideas starting to spend to much money..07 plate cdti 2.2

Hi Geof,

I recall two of your injectors were badly out of balance. Have the garage checked those? And is the inlet manifold thoroughly clean?

Can you ask them to run a compression test on each cylinder? The car did have a remap on it previously which I've solved but the damage may already be done..

Fuel filter won't be causing that missing Geof.. it was the middle two cylinders out of balance. 1 and 4 were spot on.. I suspect possibly very badly blocked inlet around those two injector ports.. or maybe a knackered cylinder head even.

Just found out that the injectors are "leaking" i washed the engine down and got a bit to much water around the injectors which started spurting up (engine was running) so it seems that they are not seated correctly!!!  So do i take them out if so how do i check the seats!!Thanks

Can you tell if it's the middle two?

Remove the stretch bolts and ease the injectors out, they may be seized in so be careful not to damage the alloy block.

Clean the seat of the injector port and use new washers from Honda.

Don't damage the alloy thread..

This may sound daft but how do i clean them and stop any muck going into the cylinder?  also they have all been taken out so hopefully it will not be to much trouble removing them again

 

Thanks

I used an injector seat cutter plastered with grease to clean mine.
Of course, you don't want to cut a new seat, just clean it, so you don't need to apply loads of force.
The debris from the hole sticks to the grease.

This is what I was getting out of the seats.

As Fahad says, it's important that you use new copper washers to seat the injectors, or that you anneal your old ones. (I get them cherry red with a plumbers torch, then drop them in a mug of cold water)

Same goes for his comment on the stretch bolts that hold the injectors in. Make sure the bolt threads, and the threads in the head are spotless before you install.

P1237 is actually a boost error Geof.. it's possible the sticking turbo is causing your misfire.

Not really, it's just a turbo.. but I'm really a bit confused with this one if I'm honest. That missing is on two cylinders

Bang  the turbo has gone ...smoke everywhere had to stall engine as it started to race!! and the ignition key would not shut it down (assume oil from turbo was keeping it running ) so turbo off next and inspect for further damage ...anyone know where i can pick up a reasonable priced turbo ....as long there is no engine damage!!!!!rogue car!!

All the shrapnel should go down the exhaust if it goes anywhere.

Even if you had any of the cold-side assembly go up the boost pipe, it'd do well to get past the intercooler.

The turbo cartridge from the civic's the same, but you need to use the accord housings. (My current turbo's made from civic and accord parts)

Hi, any decent mechanic can swap a turbo on this car. Quite a few members have actually done it themselves..

It's not that bad a job TBH.
The worst bit's slowly working all the nuts off without shearing the studs.
At least you stand half a chance though as honda use brass nuts.
