Help... Intake... Searched...

okay so I took apart my intake and replaced the gaskets, put my EGR back on (it wasnt running right without it). replaced all hoses with holes and what not. and it I may not have gotten the 2 cables on right, but it wont run now. it would start, then rev up to like 4k. then cut out. now it wont start at all. uuugh. I need a plethora of your s4 n/a intake pics!!!!!

Are you talking about the intake manifold? What 2 cables are you talking about?

More details and explanation of the "2 cables" is definitely needed. Also, the EGR doesn't affect how to engine runs in any noticeable way. It sounds like you may have had a vacuum leak created by a bad seal on the block off plate, or the vacuum nipple was left uncapped, etc...

Did you remember to connect the Air Flow Meter (aka MAF)? It will do that too....

i checked the AFM because i did that before. the egr thing was capped off, its now hooked up. and there's 2 cables. one that comes from some black canister on the passanger side, and the throttle cable coming through the drivers side firewall. i have them hooked up but i'm not POSITIVE they're on there right. so if you guys have pics please post!!

The throttle cable and cruise control cable. You had me thinking battery cables or something, which are obviously unrelated. Each cable wraps around the throttle assembly, and then has a couple of nuts to attach to a bracket. I don't have any pictures of it, but they really only go on one way. They should be taunt, but not overly tight. When you press the gas pedal, does the throttle open? If so, you've likely got it right.

Well they're on there but I did notice that before my throttle would open immediately when pushing on the gas peddle. Now I have to push it about 50% of the way before I can feel it open.

Yeah, you have a bunch of slack in the cable, so adjust the 2 nuts that lock it in place.

Okay so i switched out my MAF sensor with my buddies. No difference. I took everything apart and noticed that the threads on the bolt for the Left (or far rear) of the lower to upper manifold were stripped. It actually broke, so I had a bolt in there, and the threads on the manifold broke as well (lower side). So I got a longer bolt and put a nut on the backside so its tight now. But it still does it. And on top of it I found that my fuel rail (I think its my secondaries) is leaking (the one up on top).

To be more specific, when I start the car, it rev's up to about 4k, then jumps up to as high as 6k. and it scares me because the car's doing this from a cold start. I started the car, ran up front to watch everything, see if I can catch anything. Thats when I noticed the fuel rail leaking fuel all over my red-hot RB header. I cannot figure this crap out! Can someone post (or link) a full vacuum diagram of the S4 N/A? Ive looked and cannot find one thats better than the ones under my hood. And where is the best place to get a new Vacuum hose KIT?! Please no more than $100.

PS. I installed new upper and lower manifold gaskets, Greased before install. Still nothing changed. This all started when I went to take off my EGR valve and installed a block off plate, and capped the vacuum line.

P.S.S. Blue smoke on ignition...

Vacuum line is very cheap, a kit might be a bit more. I got 10ft when I redid mine for like $10.

Okay so I fixed the fuel leak. It was one of the O-Ring's that go on the injectors. I have a bunch of other injectors hangin out so I just switched it. But yeah its still revving up really really when I start it... then dies...

Sounds a lot like the cruise control cable is holding the throtttle linkage open. The cable near the charcoal canister is the cruise control mtr. Disconnect that cable and see how things go.

so it just revs up on startup and dies? Get the FSM and look over the vacuum diagrams or there should be plenty on the forum here if you search vacuum for title only. What I would do if I were you is pull the upper intake manifold off, start looking over all the vacuum lines and make sure you have everything routed correctly. Yes I know it sounds extreme but this is the best way to know what you did wrong. Especially pay attention to what you messed with that made it do this. Double check all your electrical connectors (TPS, BAC, ect...) and torque everything properly. The broken bolt is a sign you probably applied too much torque, its only meant to be tightened to 14-19ft/lb (not much at all). As far as the intake gaskets, i like to apply a small thin layer of RTV (gasket maker) just for peace of mind when I work on the intake manifolds. Take your time, look over everything, you will get it running if you have the patience to look over the components again....

Okay so I did just that. Took everything apart and checked over everything. I had to lines in the wrong spot. Switched them and no difference. I did however find that my ACV gasket is chopped. New one will be here monday.

put a block off plate in place of the air control valve. it will run better with that damn thing gone. and with the running issue, you have got to check your coils. i bet you have a bad coil. probably the trailing coils.

sorry. didnt notice that you already have removed the acv. go to an auto shop and get a roll of gasket. not the cork kind. cut your own gasket. it only costs about 8 bucks for a 2 foot roll.

Use RTV gasket maker, you don't need gasket paper. I use the copper type so it withstands the heat. You will be fine with this.

Just re-read your thread, blue smoke on startup when it didn't have it before I guarantee you its an improperly routed vacuum line....

You should pull that fsm link I PM'ed you and look it over, not much to it, we can probably look over your setup if you post pictures of the lines.... What happens when you uncap that one line you capped off?

Can you post some pics throttle cable and some other area's.
Also buying 2 feet of gasket paper will save you some time waiting for parts and is much cheaper.
