i put the fc tb on a few days ago and i have a few questions. when i first put it on and took a drive to test it i had a problem with it sticking. i would be driving and when i needed to come to a stop the revs would climp to around 4k. i took it home and adjusted the screw and that problem seems to be solved for the moment. but now my car idles at 1500 and sometimes climbs to 2k at idle but then backs off after a few seconds. does the spring need to "break in"? or have i done something wrong? i have an autoX tomorrow and if i can't get this solved before them i will take it of and reinstall it after the event.

No the spring does not need to be broke in. I had the same problem until I changed the throtttle position sensor. That solved the rev problem.

Hey tools,
Give more details. I have the same annoying problem with my idle. Exactly how did you change
it? Do you mean re-adjusting the position or a
installing a new sensor?

...just a thought. Did you try calling Focus Central? They kinda made the silly thing, and would probably know how to make it work. Since they made it and all. And, oh, yeah, they're friendly too.

tools- i hope it's not the tps, my car is only 6 months old.

RainyZX3- i'm well aware of the fact that they made it. it's not hard to figure out when their pretty logo is stamped on the damned thing. i was under the impression that they were closed on the weekends and i need this problem resolved before tomorrow. thanks for all your help though.

my throttle body sticks too, i have heard that it is probably the TPS. in fact my car has the exact same problems you are having with the FC TB. i'm planning to replace the TPS, but first we're going to try to clean it as it may have become dirty during the install (small pieces of rubber/plastic falling into the intake manifold by accident.)

don't let some peoples' posting offend you too much. there are more than a few people that are quick to say "fix it yourself" or "do a search" because they don't know what the hell they are taking about and want to be a smart ass.

god forbid someone post a question on an internet forum about a product that dozens of the forum's members own! when will you learn? forums are only for bitching about movies and sharing pornography.

and thank you nate! that is exactly why i posted about it. i searched for answers to my questions and came up with a few, but nothing concrete. might decide to clean the tps but i don't see how i got dirty. there can't be any pieces of plastic in it because i didn't bore the intake manifold.

I had a sticking condition with my FCTB. I readjusted the idle up a hair. The throttle plate seemed to be sticking in the full closed idle position. This has cured the condition..."knocks on wood".

 

[Bantha Fodder]

I have one that is sitting awaiting installation, and it came with the "closed" position set so that there is a tiny gap around the throttle plate. If I backed out the screw very much, it would cause the plate to contact the body itself.

I would think that this would be a no-brainer. Did they ship a bunch with the idle screw set incorrectly or something?

Welding Rod: yes, there are instructions, but they are pretty terse. The directions are pretty basic, along the lines of "remove the old one, put the new one on." There's a picture showing how to connect the TPS, since it's different for automatic/5-speed throttles.

Spike,
I didn't see if you indicated what year your Focus is, 5 speed or automatic, and wether or not your throttle body has 3 sets of TPS mounting holes.

There should be 3 sets of holes for the TPS. One set for the 00-01 5 speeds, another set of the 00-02 automatics, and yet another for the 02 5 speeds. The symptoms you describe sound just like my 1st throttle body, when they only had 1 set of holes and I put it on my automatic. Early customers with automatics will recall having to send their t/b back to have the 2nd set of holes drilled...

What year is your Focus, is it a 5 speed or automatic, and does your t/b have 3 sets of holes?

 

[spike]

i have a 02 5-speed with cruise control. i don't remember seeing 3 sets of holes for the tps but i'll double check tomorrow.

BTW- the tb hung again on me at the autoX today. at the end of my runs, the revs would stick at 4k for a while. it did it again on the way home.

besides this one problem i'm having, i love the tb.

If you don't have 3 sets of holes for the TPS, there's your problem. The 2002 5 speed TPS is mounted differently from the 2000-01 5 speeds.

I have a early 2000 Focus and bought my FC TB just a couple weeks ago, when I installed it at first noticied the "sticky pedal", adjusted the little screw and Voila! Car ran GREAT for a couple days till the fuel pump started to end(it was already kinda bad). Anyways, new fuel pump is on it's way... But talking about that four days with the TB, WOW... Freed up everything, was the mod that I needed....

Let's just keep in mind that the "sticky pedal" and the "sporadic revs" are two different issues.

<font size="2" face="Verdana, Arial">this is the "sporadic revs" issue. like i said, i'll check tomorrow to see if there where 3 sets of holes. i do have another question for you though. if there is 3 sets of holes, then which set do i use for the tps? thanks for the help!

<font size="2" face="Verdana, Arial">ya know, i didn't bore mine out either, but i did use a fair amount of RTV to seal the TB. baconzx3 has gone through 4 IAC's with his TB and we kind of think that maybe the immense opening, allowing a massive flow of air, is causing excess dirt to enter the intake manifold. it's feaseable, but a long shot. i'll let you know what i find with mine.

[bartlomiej]

is this a problem with the automatic transmission focus, manual, or both?
....tek

 

[Welding Rod]

I have never heard of anyone adjusting a throttle plate to close fully inside the throttle body. If you do it will both stick and wear a groove into the TB. The plate should always remain open at least a little. Don't these things come with instructions?

<font size="2" face="Verdana, Arial">For the 2002 5 speed, it's the 3rd set, but I don't recall which set that is...

check the instructions that came with it. I'll take a picture of one of the t/bs tomorrow and scan the instructions as well and keep them on my site for future reference.

i'm good to go. called nader and got everything worked out.
