Me and my lil brother now have the same car except his is an s5 and I have an s4 but both red gxl's but mines going black as soon as funds roll in enough of that here's the problem he can turn and open and close his 5th & 6th ports but on my car I can only move them about a 1mm does this mean there stuck???

Icemark

yes, yours are stuck

avoid

so thats why Im getting such bad gas mileage thanx for teh help

ZachSpazz

Nope. You're getting bad MPG due to something else. The 6-ports control the top-end power of your engine.

well.. depends how he drives it.. if hes up top the powerband all the time and its a tad starved for air.. then.. i would imagine that it would at least contribute to bad gas mileage..

but usually bad gas mileage is a worn out O2 sensor..

soak the actuator rods in WD-40 or liquid wrench for a day or so, then go at it lightly with a hammer and see if they free up. if not u have to take it all apart and clean them and if you go to that trouble you might as well use some pineapple inserts for $50.00 or you can just wire them, stick them open (hammer works for that too hehe just don't hit it too hard!!!)

yup go with his idea. I cleaned mine but now regret not getting some with PR inserts

hehe I didn't have the patience so mine are wired. the 6 port 13B is so low on low end power anyway but thankfully the torque band is really broad (peaking at 3500 on a stock motor I think). It would bother me on a V-Tec motor since the torque peak is SO high...in those motors it takes revs for torque to grow and grow, just like the HP curve but on our cars the torque curve peaks LOW and stays pretty flat so I don't care much about losing some pulling power before 5K or so bc the powerband stays relatively the same.
