its a kade. my car finally started but the wierd thing is i didn't do anything. it just started right up but when i pass 3,000 rpms the engine startes to bog out. what could it be. and after like 45 min of driving the car, the bogging gets closer. first 3,000 and then 2,500 and then 2,000 untill i can't even accelarate but when i turn the car off and then turn it on after a few hours it rides normal but after a while continues. any suggestions. ???????
