uneven vanes will make the idle fluctuate. during that hr period of idleing it probably couldn't find a steady idle flow to learn so it just starting going up and down. but pull that code you never know.

something to do with the throttle actuator control
The electronic throttle control system (ETCS) controls the throttle valve opening. The system is composed of the throttle
actuator, the throttle valve, throttle position (TP) sensors A and B, the throttle actuator control module, the ETCS control
relay, the accelerator pedal position (APP) sensor, and the engine control module (ECM).
The APP sensor is operated via the throttle cable to determine the accelerator opening value when the driver presses the
accelerator pedal. The accelerator pedal opening value is converted to a signal in the APP sensor and transmitted to the
ECM to compute the target position. The target position signal is then transmitted to the throttle actuator control module.
The throttle actuator control module determines the throttle valve target position according to the signal received and operates
the throttle actuator to move the throttle valve to the target position. The actual throttle valve position is determined by
TP sensor A installed in the throttle body.
The throttle actuator control module compares the throttle valve target opening angle and the actual throttle valve opening
angle from TP sensor A, and when the difference exceeds the specification, the throttle actuator control module transmits the
malfunction data to the ECM. When the ECM receives the malfunction data from the throttle actuator control module, the
ECM detects the malfunction of the throttle actuator system and a DTC is stored.

Also Check for poor connections or loose terminals at the throttle body.

Pm me if you any assistance.

thanks Rene. yeah, the problem is definitely with the throttle body. the manual said to check for loose connections, and to test it with a HDS. if code is still appearing then clean the throttle body.

stock airbox is now back in and i had the code cleared. if it happens again, i'll take it to Honda. my brother works there so i get treated well.

I had this EXACT problem about 2 days after installing my old Weapon R intake...problem immediately disappeared after returning to stock. I'd put money on that it isn't your tb, but a problem with your vanes.

i doubt its with teh vanes...people have aftermarket intakes that have no vanes, people have completely gutted their intakes(including removing the vanes) and i have done pretty much the exact same thing as qhooter and i dont think any of us have experienced a problem such as this.

missing/defective vanes may cause the car to have a bad a/f...but it should not cause any kind of jerky idle.

i think this is just a coincidence of somthing wrong with the throttle body.

On the contrary, several users on this site (including myself) have had problem with aftermarket intakes causing this idle behavior...a search for intake problems on this site will confirm that. X, correct me if I'm wrong, but this is one of the major problems that prompted you to create your own intake. Yes, missing/defective vanes cause a bad a/f...and that causes the poor idle.

Even if Qshooter's problem was unique, you're saying that a completely different problem with the tb occurred within inches of modification of the MAP sensor and there is no connection between the two? And a return to the stock intake corrected the problem? I really doubt it.

im gonna have to agree w/ this one. thats almost TOO much of a coincidence.
____________

Also, Jordan... I still think part of your issue (with low readings) is partially due to your 70mm exhaust. That piping just might be too large and with the amount of flow through the exhaust, the actual air may not be being forced out because of the larger piping (i know what i mean but i dont know how to express it)

However... after thinking about it more... if you had this issue then Will wouldve had it as well, so i could easily be wrong. But the larger piping could also explain Oriol's 'low' numbers as well.... i dunno.

We'll just need to go to bristol again. try and convince them not to sell their dyno equipment.

Have you recieved the email yet with your charts? i havent got mine yet

From what I've seen, we all may have the same cars with the same engines...but there are huge differences between how they act. Earlier in this thread there were people with huge differences in stock power. And, as nighthawk pointed out, there are Si's that work great with aem/injen/etc
