Hi Jose

1st trouble

not as strange as you think...

Turn the ignitionkey a LITTLE bit left and right when the engine runs... what's happen?

If nothing happen, so it can be the "Lenkstockschalter" (steering column switch?) whitch has kopper/brass shifters they often carbonize (verkohlen) or sometimes bad connection, so dismount the whole part and watch what's going on inside.

2nd troulbe

take the plug from the lambda out, the small single wire... watch attachment
