ive found a few black streams black on my driveway here and it looks like if it was coming out of my exhaust. Could this mean im running rich or something?
I mean, theyre about 2ft long. I put my hand on the back of the muffler while the car is idling and my hand smells completely like fuel and my fingers get a bit tinted. Also, i tried turning the fpr down or up and it doesnt change readings. Sometimes i open the hood and its marking somethign else!? tightening teh fpr bolt opens pressure and untightening closes it right!?
