Hey everyone,
Just replaced my old stock airbox with a new cone filter. I had to do a little remod, but I love the sound! Last night when I installed it, everything was fine, but this morning when I started to drive it, the check engine light came on. I looked through the forum, and I know that I need to disconnect the batter cable after taking off the oxygen sensor, but do I need to leave it off? (Probably a stupid question, but ya know) And if I do, will it have an overall negative impact on my car? BTW it is a 1999 max GLE.
Thanks guys,
T.R.
