The annoying high Idle (Yes, I've searched)

[jeffnhiscars]

The screw is inside the part with the yellow stripe. Rather than an ICV delete I used the $1.99 HF ICV Repair Kit. It eliminates high idle and still allows you to fine tune your idle. Works flawlessly :p

I feel really stupid asking this, but where is this screw you are all talking about? I still can not find it, and if it helps, I have an 85 318i, not an 84 if that makes any difference.

YOU SHOULD! ;) lol it's a throttle stop, so it's on the throttle body. the screw you adjust from the bottom. there is a nut that holds the shaft in place. I think it's like 8mm, once it's loose you can unscrew/screw the screw to configure the throttle stop.

I don't think the model year makes a difference. follow the intake hose to the throttle body and you should see the screw. you might want to spray it with penetrating fluid before you try to adjust it because I broke mine and had to use some pliers to adjust it... sigh.

the screw on the TB is a throttle stop. and you only need to cap 1, but the other will let contaminates get past the air filter. one actually goes to the intake manifold, obviously.

I don't know why you would jumper the connector... is it gonna throw a CEL? LOL edit: yeah, isn't that causing a short? don't do it unless you have some load there. at least a resistor.

you have to cap both areas if using the throttle for idle. one directly lets air into the manifold as mentioned, but the other not only bypasses the filter, but it also bypasses the afm giving you another problem.

fwiw, i did the icv delete and never regretted!

oh yes, good point. I don't think about these things because I'm not using that restrictive piece of shit. lol

I do feel pretty stupid after reading through all of this, so thanks to the posters who answered all of this.
