i have a new 3800 engine in my buick and it runs really bad. how can i fix it. when i hit 5,000rpm's my check engine light will blink and stay on for a couple of days then go off. my AC is shot and i think i need to replace my air condition compresser. my climate control gauge half of it doesnt like up is there a light in there that i have to change? and how do you get the wheel covers off. do you have to jack the car to get them off? and last when i start my car it wont stay on it turns off. and i have to restart it again and give it some gas. how do i fix this?


I think this is all i would be very greatful if someone could answer all of these questions. and it would make my car so much better. i like my car and its nice i just need it fixed.
