hi everyone. i have problems. I did the quad intake swap on my 99' z24 and i am having some problems. I think it is a vacuum leak, but im not sure. I have the oil catch tank open to air on the side that is supposed to go to the stock manifold ahead of the tb. I have the brake booster hooked up to the quad tb along with the map sensor and accessory vacuum. when i start the car, it runs normal at first, but when i start driving, it starts reving to 3000rpm with no throttle. it only does this for a few seconds, or sometimes a few minutes. every time i shift, it revs to 3000, every time i stop, it revs to 3000. please help me figure this out. i was thinking it was either the evap canister (because it takes a few minutes to start doing this) or possibly a leak that opens up when the engine warms up? i hope it isn't the intake manifold gasket (but it shouldn't be because it idles fine and doesn't sound like its leaking) i don't have egr. someone please help me!!!!
