Quick fix is to remove linkage cover at cable end and give the throttle stop plate on lever arm a twist up with vise grip or pliers toward stop pin. Idle will rise slightly, but valve won't close hard enough to jam. Simple five minute fix, no cost.|

HOLY OLD THREAD FROM EONS AGO!!!!
Yeah, this thread is 2yrs old guys. Check right above the avatar and you'll see the date of the post. Typically I ask that members start their own threads on their problems even if a thread seems to be the same issue. Seems to be, and is the same issue is not the same thing. For example: ebrunke is having problems with an 03 Focus. The sticky throttle body problem is associated with the plastic TB 05+ models not the earlier Focis.
Ebrunke, I think your problem is the throttle cable. You should pop the hood, work the throttle by hand, and see if it sticks, if it doesn't, have someone work the throttle in the car. If that still doesn't cause it to stick, then you should start checking out vacuum. Your engine is known for having issues with the PCV vacuum line, and that typically causes idle issues which might explain your uncontrolled acceleration- although that's the first I've heard of that problem doing that exactly.
Blue Rocket: you too have an SVT, so not the same issue as the 05+ Focis- however it could still be, so be sure to check out that TB and clean it. Now follow the advice I gave Ebrunke and see if the cable is sticking. If not, then start checking out vacuum. You also have things like the DSI clip to check out, but IIRC, that causes stumbling in high rpm acceleration. I would check out that PCV, although I don't think SVTs are suspect for that particular Zetec issue caused by the PCV vacuum line being run too close to the exhaust.
Both of you should consider starting your own threads though, as you can see, same basic result, but since you have different engines, it is most likely due to a different cause. Thanks.

|ebrunke||Hey all, i was hoping you could assist in my problem. I have a 2001 automatic ZX3. every time i hit the gas past 2000rpms and let go, the engine will continue to accelorate untill 3500rpms. I have to either throw it in neutral or tap on the accelorator and it will catch itself and be fine. If i dont pay attention i will hit the person infront of me. i cant find this exact problem online. My mechanic cleaned the throttle body but it wasnt that dirty. the car worked fine for a few months and then came back worse than ever. what do you think is wrong?|

|PiSTOLpete717||It sounds like your throttle body is full of carbon build up, clean it out and you should be okay..|

|sailor||Posted via FF MobileRight location, look for the throttle cable connecting there and that`s the spot! hard to describe identifiers since much mechanical is hidden by covers, like the cover over the pulley the throttle cable moves to open the (internal) throttle plate (or butterfly valve). TB is sandwiched between intake air hose & intake manifold if that helps..... It`s there to "throttle" or "control" air flow at the last single pipe section of intake plumbing, B4 air enters the tuned intake manifold runners.|

TSB= technical service bulletin. These are often confused with recalls- but that's not what it is. It's merely an in-house method of sharing experiences with other repair techs that might be out of the ordinary. For example, some automatic transmission shifting problems were traced by a master tech to be a ground wire that was left disconnected by the factory. Now other techs who get baffled can look up this solution if the problem is similar. It's basically the same thing as this forum is for us- except everyone is a professional- LOL.
Whether or not you can get a new TB or not, I don't know. I don't even know if you can purchase a re-designed TB.
Oh, and yes, the throttle body is what holds the throttle plate that tilts and lets air into the engine. It is between the air intake and the intake manifold. It doesn't get cold where I live, so cleaning always worked for me.
I'd like to know if there is a re-designed factory TB, what the part number is, and what the TSB number is. That would be information that would speed things along for anyone going in for this repair.

I have the same problem on my 06 zx3. Now that it's getting pretty cold in Michigan, I'm sure it'll start acting up. Nice to see a solution for it, other than having to pop the pedal down fairly hard to get it going. They must not have issued a recall for this on the 06's.
The throttle body is where your air intake connects with the intake manifold right? (rookie here). Further explanation on where or pic woudl be great!
