My car was bucking n bogging down. When driving, rpm would drop n you could not accelerate. I changed the fuel filter, fuel pump, n mass censor. After all that, I jumped it off n drove it home. About 3 miles. On the way home about a lil over half way home it jerked a little still as if it wanted to buck and bog again. It did that twice before I got home. Finally I parked in my garage n it quit. I cranked it again n turned it off. Then again. Now, it will not crank at all.
