i just finished installing my upper/lower cobra intake on my 88 fox and when i turn the car on, it hesitates and wont stay on unless i give it throttle,even then it doesnt rev up as quick as it should..i am also having trouble with finding out what connects to the charcoal filter or if nothing connects to it?? if anybody knows what connects to the T fitting under the upper intake it would help alot! thanks in advance!

The canister conects to any of the vacuum ports under the upper intake.

When you say what does the t fitting conect to , are you talking about the big t that comes with the intake ? Or is the a t fitting that was already on the car ?

You need to reuse some of the old vacuum fitting from your stock intake, but i had your issue before when i had my old cobra intake..... any way i hope this helps, theres some good pictures in this link

On the tee run one end into the big vacuum port on the back side of the upper intake. Then take the other side of the tee and connect that to the pcv valve on the lower intake.

As for the canister, you can run that to any spare vacuum port . Or connect it the the small vacuum port on the neck of the intake next to the throttle body, if you choose not to use that port then block it off, or youll a vacuum leak.

What filter are you talking about ?

[Whitestang88]

thank you that is great help!!!!!! and im talking about the charcoal filter thats held down by 3 prongs in the lower intake,thanks again ill have to try to get the hoses connected tonight

[ryanw]

Do you know where the rest of your vacuum lines go ? You also have the big factory fitting, it screws into the back of the upper intake, then it splits off in to 3 ports...... one is a big port and two are small ports. The big one gets connected to the plastic vacuum tree on the drivers side fire wall. The two smaller ports, one gets connected to the fuel pressure regulator on the fuel rail and the last small port gets connected to those really small hard emissions lines that are all togeather on the passenger side.


Remember ....any vacuum ports that are not used....you must cap them, or you will have a vacuum leak and your car will run like shit.


Did i answer all your questions ?

Good luck,

The charcoal canister vacuum line connects any where on the intake, it just needs a vacuum source. Or am i not under standing your question.......

As for you pcv valve.... that connects to the threaded tee on the corner of the intake
