Afternoon, Can anyone tell how far (once screwed right in) how many turns to wind it back out the factory setting ? I thinks it's air mixture screw on the throttle body see picture.

Also I have attached another pic, How do to remove the scuttle panel plugs/fixings without breaking them.

Yes b16b, I've had a quick search on the Net, nothing conclusive yet..
 
Just an update I've had the car on the tester and a new O2 sensor almost cured the emissions but still running rich (see the top reading) any ideas, the main mechanic is on his holiday at the moment , Do you think it is the air mixture screw on the throttle body ? The car runs fine,idles fine and excelerates fine.

Could be your cat. Throw some Cataclean into the car. Would help some bit.

If the standard air intake elbow pipe was loose where it slides onto the throttle body, would that throw the reading out?

Also the car has done less than 100km since 2013 would that have anything to do with it?

ill be honest you might struggle removing the scuttle clips if theyve never been out. I've never been able to do it so i just keep new ones on hand. if you need some i can sort you out way cheaper than honda :)

I've tried to take two out already and both have snapped, if you have a set, send me a PM, I'll need them, thanks.

I dunno if that'll affect your MAP sensor or IAT sensor. Best you check everything over and give it another go.

My car failed emissions because the cat was nonexistent. The whole inside left the chat.
 
Is your car is up to running temperature in that photo of the emissions tester? If so the only reason the CO is high is because the CAT isn’t working properly (worn out / blocked)

Yes emission tester, I don't think it was up to normal driving temperature at that time, I cannot remember?

The Cat is the original one , I will try some cleaner, then I'll have to take the CAT off.

Before I fitted the new O2 sensor the other two readings were also in the red, I was kinda hoping it wasn't the CAT.
 
I may be compeltely wrong here, but surely that not an air/fuel mixture screw given its an EFI engine?

If it is still original cat, as you stated, chances are it needs replacing. Best bet is to buy one and have someone weld up a pipe with the appropriate flanges as buying and old used one chances are you have the same issue

I've searched on the Internet , other forums in the US, are also calling it air mixture screw as well, I did think that was only on a carburettor?
I've had few chances to buy a second hand Cat but all over £200 to much of gamble.

The Cat will only work effectively when it’s up to temperature.

I still have the original cat on my car and it works perfectly.

Aftermarket is fine. I have a 200 cell cat and it passes emissions.

I will put some CAT cleaner through the tank, and get the car upto temp, and then test the emissions again. I'm working away at the moment, so it's difficult organising anything.

Do you know if the aftermarket CAT, is a straight swap? M2 do a sports CAT, same length, the only caveat is the flange holes not mating up?

I got 2.5" one to match the rest of my system. Welded a V band to it and a 2 bolt flange to match the manifold. Works fine.
