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

[KI4UJO]

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

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

[SoopaGhetto]

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.

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 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

If youre doing an ICV delete you have to block the two hoses going to the icv with some sort of cap, (i just found random ones that fit). And yes jump the connector going to the icv also.

When you say to block both holes, what exactly am I blocking? Also, do I put the wire between the plug going to the ICV (I'm assuming)? Sorry to sound very Noob-ish (even though I am here, but not to e30's).

[Deadskittles]

You Have to unplug the ICV block both holes that were originally from it and then Throw a wire in the little plug. Then you need to just adjust your idle screw<(well i don't know if it qualifies as that) and bam! Worked for me, my car starts up at about 1000-1100 and idles at like 700-800 which is just fine for me.

whoa there. M10 for life

+1000

[Interstate90]

Its an M10

Its time to put a REAL motor in it.

[KI4UJO]

When unplugging the ICV, it goes up to 3000.

Does your idle drop after unplugging the ICV?
