Well, the light was on because when you removed the cat you probably permanently disconnected the O2 sensor; so your mechanic simply removed the light bulb. The problem now is that light is supposed to also indicate if there are other problems. Typically the light is just a flag to tell you that you need to run a dignosis (for recent vehicles OBDII). Problems like missfire, ignition and many others may not be caught because of your configuartion.
engine warning light
just what does the engine warning light do....
i'm asking because mine no longer works. as when i had the cat removed, the light came on. so the benz dealer said it was directly related to that....so he removed the bulb.
now..this was like back in 1993/4.....
nothing has happened....so should i do something about it or leave it as is.
