So today I started up my STI, let it sit for about 2 min at idle, and then started to drive off. Everything was fine until I noticed that the idle began to get low and rough and there was no response when I hit the gas pedal. Instantly I received a CEL with a flashing Cruise light. I tried to read the code with my AP, but it states there are no codes to read. Does anyone know what is going on? My battery is practically dead I might add since it's about 6 years old and I just changed my plugs 600 miles ago.

 

LIMP MODE!!!! Thats all.

Try a different reader. Any other symptoms.

 

no other symptoms. I'm going to just reset the ecu and see if it occurs again, as well as replace the battery (as if it has anything to do with it)

 

Make sure your intake box is sealed fully too.

 

I have a k&n typhoon intake, could it possibly need to be cleaned?

 

You need to stop driving the car if you have a CEL & flashing cruise asap. If your AP/Engine Management tool can not read the code, you need to disconnect the Negative terminal on your battery. While it is disconnected, pump your brake pedal a few times, then re-connect your terminal on the battery..

Everything should be back to Normal now. If it continues to happen, I suggest getting your car checked. However, every once in a while, my car also throws a CEL with no code to be read. Just clear it and be on your way.
