Dead Ports
Okay, im tired of messing with my auxillary ports. First there stuck open, now they get stuck closed. I know most people say wiring them open kills acceleration, so what if i wired them half way? Wouldnt this put me right in the middle, and bought some pineapple racing sleeve inserts, would this give me okay top end without losing to much acceleration? Im just tired of messing with these things but i dont want to wire them open and lose all that acceleration.

Take the lower manifold off, note the angle of the pins inside the sleeves so that you can put them back in correctly oriented, remove sleeves.... clean the sleeves & the port holes. Check the arms in the lower manifold that rotate the sleeves for smooth rotation - these get gunked up easily - if they stick you need to free them with some penetrating cleaner and work them back & forth until they are freely moving. Put back together. Don't forget to use some gasket sealer on the lower manifold to block.

Half open would have the same result as wiring them open.
Either wire them open (thus making you car slower) or suck it up and remove the lower intake to clean them properly.

No need to be such a dick, i asked a question that you didnt even attempt to answer or tell me why its a bad or good idea, im trying to learn thats what thats all about, you just went on about the right way to fix it, which i didnt ask, this reply was just as pointless as your claiming my thread to be, help or leave me alone, now like most people do when they start a thread, im going back and making an update on my progress. Chill the f out. And i have done all the work to my car since i bought it, its not a laziness issue, its i need to go to work i dont have time issue cause i need something to drive, someone close the thread im done with it if im just gonna get stuff like this

ok... Well I can see you are properly motivated. I apologize for my harsh words. However, the original post stands for what it is.
You can try & fix your problem without removing your lower manifold by spraying penetrating lubricant/cleaner such as PB Blaster and working the action back & forth.
The more critical question would be do you have the proper amount of back-pressure at the appropriate RPM's to activate your ports? This is the problem you will have to deal with. How can I activate my ports when they should be? How can I know its working? Why the !#@$ did Mazda stick me with this problem? It's truly maddenning.
I've been there & done that & had to invent my own solution. Search my posts & you will see. It was not easy or cheap, but I got what I wanted. It is possible but difficult. Sorry the factory setup sux.

Well good... it seems like you are strongly motivated. Keep at it. You are deaaling with the most popular problem.
If you can achieve proper port motion without removing the LIM(lower intake manifold) then you are one step closer to making it work correctly. Finding a way to make it work correctly at the correct rpm is another matter. There are several ways to do this.
I should tell you that an s4 has a difficult path to follow. S4 works from exhaust back-pressure where as an s5 works from the factory air pump. When changing the exhaust to something better you shoot yourself in the foot so to speak. It just doesn't work very well. Most guys just go turbo and forget about it.

The first pic is the whole thing (yes im missing half of my left index finger) The second is the groove that grips the port, and the third is where its flat on the other end so i can turn it with a wrench
