Back to my problem.
Car: Mazda Xedos 9 2.3 Miller Cycel Engine with AT and AC.
My car was at the oficial Mazda service in Bratislava, they replaced the oxyngen sensor (lambda sonda). After the visit, the car is no more tha car as before.
First need to be mensioned, I have the screenshots form computer, both oxygene sensors are working right, my idle rpm is set to 650 rpm.
Where's the problem?
When I am in drive mode "D" or "R" position on AT (D=Drive, R=Reverse), and I have air condition runnig, when I stop my car (e.g. on crossroad), engine stalls. This is new situation after the service visit, year ago till today, everything was OK, nothing similar happens. When I have AC switched off, rpm seems to be around 650 rpm. But when I switch the AC on, rpm drops down by approximately 300 rpm, little bit over the first thick line. But when I'm in drive mode, it drops dow under the thickline and engine stalls.
Is there anybody with some experience in such issue?
Thank you wery much.
