A last chance at helpful advice...
..before I rip my hair out trying to figure out why my exhaust smells so bad at idle and cruise.
It's a b16 with a t3, 450 injectors with a vafc set at -40% below 3,000 rpm. My timing is 12 deg tdc for vafc compensation. When I start the car up, and let it idle, I want to puke from the toxic smelling fumes. I get no smoke...if any at all sometimes a very small white whisp here and there at idle. My coolant level and oil level stay good, my compression is perfect. Looking at my tail pipe you can see build up of a substance. Wiping it with a white cloth leaves a black smear with hints of neon yellowish green wetness. Can this be fuel and not coolant? Its starting the car up, driving behind it, or coming to a traffic light that is almost untolerable. Its a very toxic smell...I would think it smells like fuel. I do not have a catalayic converter just a straight back, do cats also reduce smells greatly? Do all cat-less cars smell like ----? My only thoughts are that maybe an injector is stuck open, or my retarded timing is igniting the fuel way to late? if it was oil I would get black, blue, or gray smoke with exhaust smelling this bad right? Any suggestions are welcome. |

Re:A last chance at helpful advice...
ya thats fuel smell probably. Yes a non-CAT will smell a little worse.
what are your VAFC settings @ 1000rpm/lower/idle? |
Re:A last chance at helpful advice...
I have this problem in a non-cat exhaust. I just got used to it, and drove with the windows down.
