yep you heard it here. Just did the airbox mod with yesterday with the AEM dryflow, unhooked the neg. of the batt for a couple min then put it back on. Drove for about 25 miles and i got a CEL so this morning i unhooked it for longer(10min) then it went away and then came back in a couple hrs.



before u ask yes it was the dryflow filter im not dumb. any advice, suggestions, help would be very appreciative

anyone!!!

Is the maf connected properly? Did you get any dirt on it at all?

Go to autozone and get a free codescan and let us know what code it is. That will help out a lot. For now i'd re-check the MAF connection. It's probably just loose.

well c i had some probs in the begining so i just tryed to twist the box out etc....yes my hands were dirty when i grabbed the filter, i hope i dont have to redo it haha

erockxp

wow I can understand your frustration since I got the dryflow to AVOID CEL's, not have them popping up and what not. I would say clean the MAF and unplug the battery for longer but who knows? My friggin' balt will throw power steering codes along with security codes along with a festival of lights at the dash sometimes. As long as it still runs, warranty gone bye bye today at 36001 miles!!

i dont even know were the MAF is

Super_SS

its the sensor that connects to the pipe on the intake box..located inside the fender well behind the drivers side fog light

EceSSiveMod

can i get to it without taking the wheel and plastic out...that was a bitch

nghisus

It's the sensor that is retained in the tube by 2 screws. Get some QD Electronic cleaner and spray it after you remove it from the car. If problems persist its probably the way is is flowing through your intake.

You can always take it to Autozone to get your code checked for free to really make sure what the culprit is.

krazycobalt

I have had my Injen CAI for 6 months and no CEL, but i was very very caraful when moving the MAF sensor from my old one in to my new one.

just so you know if you decide to pull the maf its easier to get through the headlight socket just pull the headlight rather than the wheel well

and double check that everythings tight not just a visual inspection and also check the vac line on the tube between the throttle body and fender

EceSSiveMod

ight cool anyone else???

JPizzle

1.) Dealership
2.) Buy a real CAI.

LopsidedJester

check for any leaks or bad seals in the tubing for the airbox mod, Mine was setting off the same code and it was due to a connection where the rubber piece was folded in and allowing extra air to get into the intake.

EceSSiveMod

send me the money

bigrroberto

i have a dryflow filter, not AEM. Had on for many months and no cel...

Mr_Slobalt

definitely check for the filter being loose

we had a ss/sc in the shop yesterday for a similar code and the filter wasn't even on, nor would it stay on.....K&N ftl

Are all years the same , or just the 07's with the new OS? I've had a Aem CAI on for the last 3 months and not one issue, before that was an airbox mod for over a year ..no cel . Wondering if it's a fluke or bound to happen eventually . I did have a P0171 the first week i bought it new but the dealer flashed an update that was supposed to take care of the issue .

Here's the TSB


#06-06-04-033: 2.0L/2.2L LSJ/L61 Engine Malfunction Indicator Lamp (MIL)/Service Engine Soon (SES) Lamp Illuminated with DTC P0171, Fuel Trim System Lean, Set (Reprogram ECM) - (Jun 21, 2006)

--------------------------------------------------------------------------------

Condition
Some customer may comment that the MIL/SES lamp is Illuminated. Further diagnostic investigation with a scan tool may reveal a DTC P0171 Fuel Trim System Lean. No other driveability or performance concerns may be reported.

Cause
The most likely cause of this issue may be that the engine calibrations need to be updated to correct a variation in the Mass Air Flow Sensor.

Correction
DO NOT replace the MAF sensor, the ECM or any other parts.

Important:

• Chevrolet/Pontiac Dealers: The ECM calibration is available to dealerships as part of TIS2000 incremental satellite update version 6.5, which was broadcast to dealers June 12, 2006 or later. For the dealerships that use CDs, they were mailed out June 2006 or later.

• Saturn Retailers: Before installing the new ECM calibration, make sure the Saturn Service Stall (SSS) version is TIS 6.5 2006 or later.

• While the ignition is OFF, apply the parking brake to disable the daytime running lights (DRLs) prior to starting reprogramming procedures

• The technician must select the "Reprogram" option in order to reprogram the ECM.


Reprogram the ECM with the latest calibration. This calibration, or any that follow, is designed to address this DTC P0171 concern. Refer to Service Programming System (SPS) in SI for reprogramming procedures. As always, make sure your Tech 2® is updated with the latest software version

Warranty Information
For vehicles repaired under the 8-year/80,000 mile (130,000 km) emission controller warranty, use:
