I have nissan maxima 1996. I got a problem.
strong smell comes from inside the hood after driving and facing very bad gas milage.
engine stall on neutral and sudden jerk (or loss of power ) when accelerating.
sudden change in RPM position when neutral. Sometime high RPM till 1500 and sometime decrease till 300 and black smoke from exhaust and engine die after RPM get low.
note - I disconnected TPS when engine running but no changes. I done same with the idle air control valve and no changes in idle.
