    revs drop at stop light

    Hi guys, i am new here, i hope you can help me, i have a 1996 c220 with manual transmission, the thing is that the rpms drop when i get to a stop light, sometimes it stalls, i have cleaned the TB ( FOUND OIL ON IT ), i have recently installed sparks and wires and maf sensor as well but the problem continues. NO rough idle, just the reps dropping when driving and getting to a stop.
    i will also appreciate if you can tell me where the EGR valve is, i can't find it.
    and the crankcase valve also, i can't find it.

    regards from mexico

    Possibly the harness on the throttle body has an issue.

    On the pre-facelift w202 models, the EGR valve comes out with the intake manifold.
