How to get rid of Check engine light?
I recently installed some Fast Intentions test pipes on my G37 and am looking for a way to get my check engine light to turn off. If I could get some guidance I'd appreciate it. Thanks!

7. Fully depress the accelerator pedal for 10 seconds. At this point the check engine light should change to blinking slowly

guys dont bash if you arent a veteran of modding vehicles. buy a mechanical o2 sensor bung. screw into oriinal o2 sensor location as a spacer between o2 sensor itself and exhaust. it raises the sensor out of the exhaust stream causing it to sense less oxygen. it worked on both my sti and evo

test pipes
the ecu looks at the rear o2 sensors to see if the cat.converters are above 70% efficiency, you can clear the codes but as soon as the ecu runs the monitor test the check engine lite will be back on!
