Metal bolt stop under gas pedal

[m3f_Krank]

I was wondering a couple things about it, I figured there had to have been a thread about it before but nothing came up in search.


How do you know where it's supposed to be set? It's just like a clutch stop and can be screwed more inward or outward. How do you know it's set to a level that would allow you to go 100% WOT.


Would screwing it in a few millimeters harm anything? I know it may not yield any beneficial results but would it possibly be harmful? As in breaking something in the throttle body, etc.?


I was putting in a clutch stop today and just got curious looking at it.

Yeah I've seen it before, but I figured it's set for the car to perform the best. Maybe someone else can chime in.

You know it's set correctly if you can preform the procedure to adjust your throttle cable 100%. I believe it is mainly there to provide a stop so don't break your TB.

Yeah, I figured that too. So I was playing around with it, and when you set the bolt in further in and press the gas all the way down, it will actually go to the stop without any kind of resistance. I take it this can't be good for the throttle body? At any rate, I'm going to return it back to it's spot before something gets messed up. I hate my curiosity sometimes.

The stop is used to keep you from ripping your cable apart, the throttle body is in no danger.


No, you should not adjust the bolt.


If you really must answer your question yourself, pull the boots off so you can see the throttle body and have a friend press the gas pedal. You'll see it'll make a full sweep just fine.


DO NOT mess with that bolt or overtighten the cable. It sucks so bad being stranded because your cable snapped.

It also sucks when you botch the remove of the TB cable and break it during a manifold install and reduce your WOT down to a total of 20% of normal.

lol, my rubber stoppers are so jacked up, don't remind me

Makes sense. I didn't want to touch the bolt but somehow, I ended up touching it...



So there's no way it would ever force the TB to actuate more than its intended action, it would just force the cable to tighten and manipulate the hosing it's housed in?

Ummm, when the butterfly is open full throttle it is at 90 degree to the body. If you pull it more than that you just restrict the air, by it closing the other way.

throttle body cable tension can be adjusted on my E36 S50B32, that's where I play with the settings. When I got my car there was a bit of delay in throttle response, so checked the cable and it was sagging. A quick twist of the tensioner solved it.

I remember in my friends STI the position of this got changed when he redid his interior, and for like 6 months after, any time he went above 100% WOT, his car went into safe mode which kills all the power.

Krank - did you learn anything different here than from your same post in Bimmerforums?

I was looking at it again today and think I answered all of my own questions. I'm going to pop the hosing off tomorrow and watch the TB with someone hitting the gas. Thanks for all the help.

Wonder if that was sarcastic.



At any rate, only reason I do is because there are some very knowledgeable members over here that don't read Bf.c, and vice versa.

So your butterfly wasn't at exactly 90 degrees?



What does everyone else think about that? I'm going to pop the boot off and adjust mine sometime soon, didn't get a chance to today.
