1986 2m4 5 speed Just a stupid question, my car makes a fume exhaust smell, no smoke to be seen in as black smoke, but if you started the car in the garage for 10 seconds or so your clothes smell of exhaust. Would it be that I don't have an EGR valve and a catalytic converter?
Th car will run rich for a while when it's cold. As soon as it goes into closed loop, the mixture should lean out, but may still be slightly rich. First suspect of anything failing would be the Oh2 sensor or the Coolant Temp Sensor. The one for the ECM-fuel injection, not the one for the gauge. It's located down at the bottom of the thermostat housing, positioned horizontally.
Even at cold start it shouldn't smell rich, at least not without putting your face right next to the tail pipe. If the exhaust smells rich, then the cat is probably hollow already, if you've still got one on. Or you might have a leak before the cat, possibly at the EGR, or at the manifold.
If it smells more like gas than rich exhaust, you probably have a gas leak, likely at the fuel filter or at the line leading up to the throttle body (or fuel rails on a V6).
