Default 2007 STI with AccessPORT V2 set on stage2 (check engine light flashing)

Just put on a Perrin Catted dp, SPT cb, and ARC intake. Set the AccessPORT on stage2 91 octane. ( but I only have 93 in my area ) Every now and then the check engine light starts flashing. Getting a Pro Tune in a couple of weeks but what can fix this problem till then? Sorry if this is a double post I just don't have the time to read thru all the forums.

Thanks

A flashing check engine light is usually related to a more serious issue like a misfire, so try to read the codes using the AccessPORT. How many miles are on your car? How old are the spark plugs?

The car has 20,000 miles and I just tuck it out for a ride today. Code said that it's running to lean.

A running too lean code (P0171) is likely due to the aftermarket intake that you have installed. Only the stock intake and the Cobb SF intake are compatible with the OTS maps. You can get a custom tune from a protuner for your intake or you can put either of the intakes just mentioned on if you plan to stick with the OTS map. If you do the latter, make sure you reset the ECU via the AccessPORT's troubleshooting menu. Using the wrong intake can cause major problems as the intake determines airflow and load, which ultimately determines the fuel target, the fueling calculation and cam/ign. timing.

You can check the A/F Learning 1 A, B, C, D monitors via the AccessPORT's live data feature (loggable as well). These are your long-term fuel trims. If it has been a good amount of driving (at least a week) since you last installed the AccessPORT, reflashed a map, reset the ECU, or disconnected the car's battery, then those should be populated with representative values. Each one should be within about +/- 5%, with outside of +/- 8% indicating a potential problem.
