    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.

    revs drop at stop light

    Hi all.
    Have got an LPG system in my Doka. Was already fitted when I got it so know very little about it really.
    Used to work fine. I had to remove engine but now its all back together the LPG has a cliche.
    Keeps switching back to petrol when the revs drop. It stays on LPG while revs are up but when I change gear it switches back to petrol. If I rev it, it goes back to gas until revs drop again.
    Tank is full.
    Where should I start looking?
