My 2006 Suzuki forenza has had problems accelerating. It shifts real hard (shakes the car) when put into drive or reverse from park. Then it is like it is stuck in 3rd gear or something and accelerates super slowly. It also makes a grinding noise for about 30 seconds when the car is first started. It has been consistently doing this for the last few months and today it won't even start. I hear it trying to spark but no turn over. Can anyone help??
