problems with my AEM intake
I just got my 2003 WRX sedan and installed the AEM short ram intake. Right after I installed it My idle time dropped just under 500 RPMs and I have a chronic engine code of bank one lean.
I've contacted AEM and they dont have any answers for me yet. Before you ask, yes the MAF is on correctly.
Has anyone seen this problem before and have a solution.
Still related to the same problem where is the adjustment for the idles speed on my car.
Thanks

Sorry to hear about that.... I have an AEM intake and while replacing the stock intake I noticed how easy it could be for something to get on the sensor. Is it possible you toched the sensor to something when you were installing and somethign got on it?
I also have heard stories that because the intake is wider than the stock pipes, it actually makes the engine think there is less oxygen because less of it is passing by the sensor. Makes the engine run LEAN, or so I've heard. I don't wanna sound like a dick, but check your screws and connections and make sure everything is tight.. if there was a leak(air getting in that doesn't pass the sensor), that might be the cause of your problem. That may not be much help but it's all I got. Good luck.

I checked the sensor and it looks perfectly clean. Also the connections are quite tight. My problem isnt not enough oxygen, its too much oxygen. There realy aren't a whole lot of things you can do to install a short ram wrong. My major concern is that AEM says they have never had a case of this happening. however I still want to find someone who knows where the adjustment for the idle speed is.

At this point im desperate to find answers and AEM isnt helping. Is it really possible that no one has seen this before?

It's not that no one has seen it before, it's tough to say without more info I guess, or without knowing exactly what you did to pinpoint what went wrong. If you have the short intake there's not much that can go wrong, installation wise.. there are so few places to leak air. The only other suggestion I have is to reset the ECU. Disconnect your battery for a while.. I think I heard 15 mins is good enough. That allows your engine to re-learn the parts your car has attached. That sounds like a pretty in-depth problem though. I would get a second opinion with someone more knowledgeable than I under the hood if none of this stuff is working. What other mods you got?

I have no other mods yet the first one i did caused a problem so I stopped there. I thought I would get results from the manufacturer and they want me to buy a piggy back computer. A little more than I was looking to do at this stage of the game. I had a friend tell me that if I put ona BOV that does a 50/50 return that it might help. Any thoughts on that.

I have an AEM short ram on my wrx and have no problems with it it sounds like you might have a vacumn leak somewhere. Try disconnecting the negative on the battery for a minute and it might reset the computer, I bought my intake used and the person who had it was getting a CEL from it, I have had no problems....

did you reset the ECU initially after installing the intake or did you do it after reading the responses?...I just want to know for my self If I need to reset the ECU after installing an intake cuz I will be doing that soon..

gain
not a huge gain. the biggest difference I noticed was that before i switched it out i never heard my BOV working at all. But i can feel a slight difference. Dont expect to be thrown back in your seat from it though. It does spool a little quicker too.

Sell the intake and do something more worthwhile for your car. Those power increases are most likely psychosomatic

I doubt it. Did you read that threat I pasted above?
A BOV works when the throttle closes to relieve back pressure on the compressor. It keeps the compresser spinning between shifts and extends the life of your turbo. It has nothing to do with your mixture.
And my guess is you are misinterpreting the code. I don't think its lean because you have all that much air. I think its lean (or thinks its lean) because you are giving your ECU confusing readings because of the intake.
Take it out. If you really are running lean you could very well be hurting things, not to mention actually losing power because the ECU would correct.
