1992 Mazda b2200

I have a 1.7 cdti diesel corsa hatchback 2002 model, No 1: I would start it no matter when but the first start,it would start but not for long then switch off,when I start I have to keep my foot on the accelerator for few sec then it will pick up,..No 2 :Sometimes when I'm driving, stopping by the robots or intersection once I put my clutch and hit the brakes it would go off,,,,No3: if I drive and hit high speeds like 160 to 180 it would show a car with a spanner on the dashboard then I would feel that the turbo is not pulling until I switch the car off the start ,,help me to solve These problems,,,

Leveling kit? Yeah they're called torsion bars. Reindex them crank them down and it will lift as you see fit
