I need help! My car is stalling when I decide to run trough the gears quick. If I, as an example, use 2nd gear to redline, when I shift to 3rd the car run poorly (stalling), but if I lift the gas pedal for a second, and push it again, the car runs as it should. It has this problem when I shift quick and near redline. On the other hand boost is OK at 0,7.
So what do you think?
PD Excuse my English!!

 

get your codes read...durametric, PST2 or PIWIS....

 

Sounds like you're running extra rich at high end rpms to safeguard your engine from running lean and blowing up. I think when you say "stall" you might mean bog. If the car bogs at higher rpms, then it is most likely to a poor a/f ratio up top or a hose leak. Definitely go to a mechanic and get it checked out. Hope that helped.
