9-3 2.2tid Vmax lt. GPS 182???

Again a question in the round: Yesterday I was a bit longer on the highway, thought it has to be looked at how the 200 feel in the Saab…Pustekuchen…Tacho 190, GPS Navi 182…it lights up but nothing anywhere…no warning or check…So from 150 it gets very messy with the acceleration…Air filter is new, fuel filter also new. Someone already had something like that, or a hot tip where to start with the search???
