Anybody in California got one of these I can borrow?
Today my car's check engine light came on, checked the code and its a P0174 which means that the car's running too lean (after 4 months of having a CAI, only now does it run too lean??) Just wondering if I can borrow a tuner so I can fix the problem, I've heard taking it to a shop is too expensive. All I'm looking for is to just adjust the Air:Fuel Ratio and I'll be good to go. I'd be willing to pay shipping/handling or any other fees that you would like me to pay for using it (as long as it's not outrageous), PM me if you can do it. Oh and by the way, I would buy a tuner myself but, I just quit my job and my funds are tight, so I'm getting a job as quickly as I can, thanks for understanding!!!
As I understand it, and I could be wrong, but you can only use a tuner on one car. For if you used it on more than one car, you would loose the ability to put one or more of the cars back to stock.
oh....gah, that sucks. I tried to erase the code with my obd-II programmer, and it didn't work, I just want to get rid of it haha. Well I guess some black duct tape will do until I can pay for my own....
On my 98 I had a similar issue. It turned out the filter had fallen off in the fender and it was sucking through an open tube with no filter.
Sounds dumb, but worth checking out.
I once saw a ricer drive over his own CAI. Not just the filter, the whole intake. It came loose, and fell off as he was pulling in his driveway. Ran right over it. I couldn't stop laughing.

OK, so I've added a few things to it. Check my Profile - too many to list here.

LOL, lets just hope that's not my problem. I completely forgot to check to see if the filter's still intact, but I did check my spark plugs to make sure I wasn't running lean. I mean I've had the CAI since May so I probably would've noticed any bad wear on the spark plugs and they're 100% perfect (I replaced the spark plugs when I put the CAI on). I doubt the filter fell off, because the car isn't do anything abnormally...

You won't be able to "tune" the car, but you CAN read codes (and erase them) with a Diable, SCT, etc.
You can also just unplug the battery negative terminal for a few minutes, too...
But whatever threw the code will still be there, waiting to do it again.
Check all the connections on your CAI to make sure they are correct, especially where the various sections of tubing mate up - an air gap leak will cause this sort of problem.

The area where the flat part of the CAI attaches to the sidewall going into the fender has a couple holes that are open, would that cause a problem? Around the outside of the CAI, the flat part wasn't big enough to cover up those holes. As well as this, I get a high pitch whistle at certain RPM's is this a leak somewhere? If so, well I gotta go to JBA Performance Center and get a tune (I installed the CAI myself and have no idea where it my be leaking from).

The whistle is probably normal - CAI's don't suppress this sound like the OE snorkels do.
I doubt that holes upstream of the Mass Air sensor will create a lean condition, unless they are really huge.
A tiny crack created by the hoses or pipes sagging (the crack usually occurs on the underside, where it is pretty much invisible) can cause the problem. If the CAI pipes were just barely long enough, and you're not catching enough of them under the rubber seals with the clamps, this could be happening.
If you have this intermittant problem (as things move around from heat and vibration, the gap may open and then actually CLOSE itself), a tune would not necessarily fix anything.
I'm mentioning this because I encountered this problem myself - I finally found the source when the pipe vibrated completely out from under the blue rubber connector!

Joking aside, I've been following your thread with interest. I threw a P0173 and P0174 earlier this year. In my case I heard valve train noise and it turned out to be serious enough to warrant a new engine. There were no clogs, but the heads weren't getting oil. They suspected, at first, that the Phram filter I used was coming apart internally. Apparently, they had some issues. That wasn't the case with me, however. The thinking now is the aluminum block failed internally, short circuiting the oil path to the heads. The tech from Detroit took my old engine back with him for a Post Mortem, but I never heard the final results.
This doesn't seem to be the case with you based on your description, and I didn't want to scare you by posting my experience.
By the way, isn't P0174 the code for "engine rich, driver's side"? I don't have the book in front of me, I'm going by memory.

According to my book on the 98's, P0174 is "System Adaptive Fuel Too Lean Bank 2".

im wondering why you werent able to clear the code. with my obd II scanner, i was always able to clear the code (provided i followed the proper procedure, which was erase the code when the ignition was "ON" but the engine was off). i recently had a few codes like that as well (P0171;P0174;P1131;P1151). turns out for the two latter of the four, it was the front o2 sensors that failed. for the first two, i thought i had fixed it as well with the new o2 sensors, but the code came back on shorty afterwards and i checked everything under the hood and turns out one of the hoses connecting the valve covers together had a rubber section that was kinda falling apart.....since it was late at night when i checked it, and all the stores were closed already, i just used some electrical tape and tapped it up nice and tight, and so far no problems at all, and its been almost a month now.
