Hey I have been telling you guys about my car not picking up like it use to. That I have rebuild the engine and now it does not pick up as much. My intake tube has 3 outlets or inlets whatever, but theres one that goes to the bov and there 2 little ones like on the side that you can see if your looking right in top of the intake tube. One of them goes to the side of the valve cover. There is the other one that is to the left side of the other one but it has no hose on it, and also i dont know where it leads to. Anybody have any idea where it goes to and if that might be the problem of my car being slower. I put the computer on it to check for the problem and I need to give it a tune up but also it says "Fuel Trim Malfunction (Bank 1)". I have no idea what that is either so if someone could help me to figure this stuff out please and thank you.

does anybody know what it could be?

The 3 connections are for the Evap canister (Should be under the battery on your car, rather large hose), vavle cover vent, and BCS solenoid. If you are no longer using the BCS solenoid, or any of those ports, be SURE to cap them off. Otherwise you are pulling in unmetered which causes a LEAN condition, in addition to the risks associated with pulling in unflitered air. The fuel trim malfunction could very well be the ECU maxing out its fuel trims in the positive direction trying to correct for the unmetered air. The effect is much larger at lower airflow levels, like idle and cruise.

I'm not sure how one could possibly connect to the BOV.

Well theres one entrance that goes to the k&n intake, the biggest entrance.Theres the next bigget tube that goes to the bov. Then theres 2 small ones that you are talking about. So I dont need to put the hose just cover it up or what do you suggest.

Never mind, you must be talking about the BOV recirculation. I thought we were talking strictly vac lines here, of which there are 3. The one for the BOV should be about an inch or two in diameter. There then are 3 vac line type fittings, the larger of them is about 3/8th or so, and goes to the evap canister under the battery. The next smaller one is probably quarter inch and goes to the valve cover, the smallest should be 3/16ths and goes to the BCS solenoid. If any of these things are not being used be ABSOLUTELY CERTAIN THE FITTING ON THE INTAKE IS CAPPED OFF. Using all caps was meant to emphasize that point, for the reason listed in my last post.

Well it is the one that goes under the battery. Is there any problems if I have that disconnected or should I go buy one to connect it. Will that make my car smoother or same thing as if i didnt have it.

Its ok to not have the canister connected, but in some areas you will fail emissions inspection for this. It wont affect the operation of the vehicle though, you should only have gas tank vapors coming out that line (so dint plug it

)

The important thing is to be SURE that you have capped off its port on the intake pipe. Do not allow any leaks between the MAS and turbo. Plug those all up and you will be fine.
