Running rich/unknown dash light
First off, a week ago, my 95 SL started smoking (white) when I revved the engine. It smells strongly of gas, and I was wondering what I needed to do to get my air/fuel mixture back to normal. I have lately had to adjust the screw on the throttle body that controls the idle. At one point the car would be up around 3k RPMs when idling so I screwed it all the way in which brought it down to 900 but after a few days the car wouldn't idle at all so I adjusted it again to bring it up to 1k. It slowly (over the course of a couple of days) got higher and higher so I lowered it again and it wouldn't idle again. I don't why this keeps happening, but I was curious as to whether or not me screwing with the idle would cause it to be running rich?
I have a dash light that I guess looks like a colleseum (its in the lower right hand section) that randomly comes on and goes off. Does anyone know what this lights mean?
