Your car will burst into flames

Damage of what?
Thats like an idle screw, messes with the amount of air/fuel that goes in your throttle.

Can't help, sorry - but nice strut bar (eibach, correct?)

[torontovka]

It means that there is air leak somewhere,, any1 has clear diagram for the system ??

thanx

It will cause you to have poor grammar/spelling.

Buy a Bentley manual and read the part about the fuel system.

I wish I could help you but I know very little about 16v stuff. I believe this is just an idle adjustment for the butterfly. If so it will cause no damage to your engine. I would try your question in the 16v forum.

For the most part this forum is good for telling you if your cool or not but not so good at answering questions.

When you sort it out please post your end result for future people with the same issue.

This is the idle air screw.
IIRC screwing in CW opens up bypass and raises idle, Screwing out CCW closes bypass and lowers idle.
It will do little harm if yours is in all the way in.
Next time look for something else to adjust, like the air pressure in the tires to get more low.

He's def right about the cool uncool thing.
In all seriousness though, buy a bentley manual and read the part about CIS. It will make your life SOOOO much easier.

There's a reason this is a dead horse on this forum, one that has been shot, dragged by a semi truck, dropped off at the glue factory, refined into glue, and then used to make the sticky side of the duct tape that holds most of these poster's MK2s together.

The Bentley doesn't put enough emphasis on clean electrical connections and lack of vacuum leaks, but can get you towards the mythical goal of good and reliable running CIS-E.

I do agree with you, but only til the part about Bentley not putting enough emphasis on clean electrical connections and vac leaks. Its a repair manual, it doesn't have to reiterate anything, if it says it once, in the right spot, that's sufficient. It is then the responsibility of whoever wants their car to run correctly, to follow god d@mn instructions. A proper running CIS car is not a mythical goal nor a difficult task. Read your manual, follow the procedures and you will arrive at a nice idle, smooth power delivery and an acceptable measure of reliability. BUT YOU HAVE TO READ THE MANUAL

This is the idle air screw.

Absolutely NOT; can't you read?
This is the idle air SCROW.

Finally. I couldn't believe helpful responses were out numbering the ones mentioning the fact he spelled screw wrong.... TWICE.

Ya, but we let it slide since he only tightenT the scrOw,,

As noted many times before, that is the idle air screw - fully tightening it will affect idle speed but won't cause any permanent damage. That said, I've raced these cars for 15 years and owned them for longer than that. During that time, I have NEVER adjusted an idle air screw on a CIS or CIS-E car because the problems are always elsewhere.

The only time I've ever touched the idle air screw is when it, embarrassingly, fell out - twice. I didn't learn the first time (or perhaps I changed throttle bodies, I don't remember) but every since, the idle screws in my cars are secured by silicone sealer to keep them from backing out causing a massive vacuum leak.
