Any secret to clearing an CES Light without a Tech II?

HOW TO SET DIAGNOSTIC MODE II (SELF DIAGNOSTIC):
1- Turn ignition to "ON" position and wait 3 seconds
2- Fully depress and release accelerator pedal 5 times in 5 seconds
3- Wait 7 seconds, then fully depress accelerator pedal for approximately 10 seconds until the MIL starts blinking
4- Fully release accelerator pedal (ECU has entered diagnostic mode)

this happens on and off only when the car is in idle. my a/f gauge (wideband) spikes towards the very lean end. the engine gets very bogged down and the CEL gets tripped. here's what code i get.
10 slow blinks, pause, 3 fast, pause, 10 fast, pause, 10 fast, pause and then it starts over again with the 10 slow blinks.
does that mean 300? multi cylinder missfire?!?! what the hell is going on? and thanks

I just installed a aem cold intake system on my 05Z and the SES light came on about 2 days ago. When I installed however I didn't disconnect the battery before taking out the MAF sensor. How can i remove this light or is that cai install the source of the problem........ PLEASE HELP
