The idle screw on my 91 CRX HF is chewed up. Can I back it out 100% and replace it? Is some spring or anything going to come out and be a problem? From the parts diagram it looks like I can just replace it.

Anyone know the length/thread pitch if I go to Home Depot at lunch?

Thank you!

 

Some one has had to have done this... right? Also, would plumbers tape be a bad idea?

 

yes it comes right out. if the slit is all chewed up just grind a new screw slit and replace the o-ring that is on it. I wouldnt use a home depot bolt

 

Does it have a special taper or something? O-ring you say? I wonder about ordering it from Honda? hmmm.

 

It has a special taper at the end, and 1 or 2 orings built into it...

I took mine out (just barely) and dremelled a new, deep slot. It also had red-lock tite on it, and was brass or some soft metal... not sure if it's original, my other CRX has a grey screw, and it is much closer to 'out' than this one... I wonder which was factory...

 

mine is grey and as you say, close to out at the stock settings. I know for a fact it is original as I am the original owner. This is the stock setup though....

 

I have seen brass screws, and other are just aged brass. If you replace it, replace it with another another throttle body. There is a taper on it, it screws into a seat that allows air to pass around the throttle plate. Loctite is not neccessary, but a good idea. Although that's how the screw gets chewed up in the first place.
