I'm having a problem with my 2001 Hyundai Sonata. It seemed like the motor would lose power and slow down. Then the power would come back and the car would quickly speed up. It has also been having a hard time starting. Sometimes I would have to try several times before it would start. I thought the starting problem had to do with the power loss problem. I had the car checked and I was told it was the ignition coil. So I replaced the 2 coils, spark plugs and wires. Now the car doesn't start at all. So I changed the starter as well, but the car still won't start. Every time I turn the key, there is a fast clicking sound. I thought it might be a problem with the battery so I tried jumping it with another car, but that didn't help. I don't know what else to try. Also, the car is a 4 cylinder with a manual transmission.
