Buickboy Usually these things pop up on ebay for 80-100 shipped. if you have a local u pull yard you might find one for 25-50 bucks.

This is the way id go if I had a 2.3, its a direct swap. When I tried to do the delete and plug the holes on my 2.0 manifold, too much was broken to repair. The inserts in each runner were cracked and it was a big mess. The escape manifold has it all done already

Yea it'll cost more then removing the flaps/shaft & filling the holes. Just mentioning thats what I'll do, if I was going to remove the flaps/shaft. You wouldn't know if they were there or not.

Once your rolling, doesn't really effect, gas it up, they're open. I'd say just remove the vacuum line from the i/m & plug & see what your thoughts are & if you like it.
I've had the vacuum line disconnected for the second half of this week and been daily driving it like this. I've been hard pressed to notice anything I don't like about it. My plan was to delete them this weekend but I'm getting mixed signals about whether or not it gives any performance boost when you actually take out the flaps and get them out of the way of the airflow. Having them open is not the same as them being gone when it comes to higher RPM. I suppose I could just do it and find out myself if there's a difference. Was just hoping somebody else who actually removed them (from a 2.3) had some more info for me.

PerroCaliente So I been running it for a day so far with them locked open. Did as you guys said and I'm really not noticing much if any difference down low. I'm not sure if this is due to me having a stealth CAI, BSD, 2nd Cat delete and straight pipe. Maybe my car just doesn't care anyway? I'm usually pretty in tune with small changes in my car so I feel like I would have noticed. That being said for those of you who have deleted the flaps, would you agree you could feel a difference in the mid/upper range at all?

Are you trying to say that your issue is due to the solenoid fault or you're just saying having them open caused a loss of low end response?
Undue the short vacuum coming off the front of the i/m on the drivers side & plug the opening on the i/m, then see how you like it= response + also notice the lower noise level= no ticking sounds.

sailor Meant just what I said, ran it for a while with a bad solenoid so they didn't close & I didn't like the performance. Got around to replacing it finally and got back the low throttle opening 'grunt' I liked from the engine.

Had it quit once before for a bad vacuum hose, this time I let it go for a while to compare operation (since some claim more power without).

Personally, I like the added power at the bottom end - that's where I use it most of the time. Cruise around & have some response avail., feels like a larger engine.


If you unplug a vacuum hose & don't plug it, you created a vacuum leak. Might be all the time or occasional depending WHICH you removed. Shouldn't be 'random jumps in power' from tumble flap operation.

What they do is give higher velocity air flow past the injectors at low throttle, helps in atomizing the fuel injected. Note the opening when closed is at that side of the intake.
