My friend got his Z out yesterday, first time since installing the plenum since we finally got some decent weather, and the SES light was on. He says the performance is fun, but he don't like SES lights. What could cause this? Is this another one of those clear it and it won't come back situations?

 

Yeah, its another one of those clear it and forget about it lights. It happened to me a few months ago when i installed mine. I reset it and i havent seen it since.

 

did you unplug the sensor from the throtle body if so that is the cause and the car might idle rough basically just resset it using the instructions from the technosquare wbiste no biggie
