Alright so i just removed the 2 butterfly valves that are before the secondary ones on my throttle body, as im pretty sure they were malfuntioning. I just put the car back together and it started fine, then i gave it a little bit of throttle and the thing went up to 3k and wouldn't come back down, any ideas?

 

could of easily just stuck open a little. clean the old worn out return springs on the TB and lube them thouroughly with WD40. also, make sure there are no leaks from where the butterfly shaft originally was...

 

Yeah, I pulled it back off the car, thinking it must be some sort of vacumn leak, it seems the secondary butterflys don't seal properly. I tried adjusting the stop, but part of it hits on the throttle body, leaving a slight gap around them.

 

while its off, port and polish it!!!

i also modified it so the butterflys open all at the exact same time. because if they dont, only the primary butterfly opens fully, and the secondary butterflys reamin slightly slanted hurting flow big time. big improvement along with porting it...

 

What do u mean by port and polish it? I sharpened up alot of the edges, and smoothed em out.

 

do NOT use WD40....

 

Why not? People will generally not take your advice without some sort of explanation as to why. Not that I'd use WD-40 either, but I am just saying.


I'd try a bit of gun oil/tool oil. It is thin enough not to attract dust and dirt, but lubricates small parts like springs and levers well.

 

Because WD-40 is a solvent, not a lubricant.
It's primary purpose is as a water displacement agent- hence, "WD"- and in the process it will clean away some gunk, which sometimes loosens up a sticky part but is purely an accidental byproduct.

WD-40 has it's uses but a lubricant it ain't.

 

I am aware, thus the reason I said to use gun oil. I asked why not, not because I needed to know, but so that others would know.

Let's say, for example, I am new to driving a standard transmission. I have never driven a standard before, know nothing about how they work, and someone is teaching me. If that teacher tells me "don't rev the engine so high to take off in 1st" and doesn't explain "why not", I am more inclined to either ignore the advice or do it anyway to see what the outcome of doing so is. Even though the consequences of reving too high may not be apparent in the beginning by naturally compensating with some more clutch slip, I'll eventually wear my clutch out.


Long winded example, and I am probably making more out of this than I should.

My point is, if you are going to tell someone to do something, or to not do something, explain why.

 

Thanks Freud.

 

So anyway, i know about wd40 so back to fixing my throttle body

 

This problem is now fixed.

 

Must we consult our Magic 8 Ball to find out what the problem was?

 

I really could care less if he ***** his car up, or you **** your car up.
But the advice is there to fix your and his broken car... take it or leave.

If someone is teaching you how to drive a stick and not rev it up, but you are stupid enough to rev it up and dump the clutch because he didn't explain why. That is like saying - Don't drink the poison, and you would go drink it because someone didn't explain to you why.

But really, I wouldn't expect less from a Texan...

 

Hot headed are we? I never intended to insult you nor did I throw a bunch of vitriol around such as you have done.

I suppose making you upset will get you to post more than just one liner replies. Hell that is the longest reply I have ever seen you type. Amazing, I am impressed.
