CRX DX 89 Automatic Well I was driving and I stopped, turned the car off in Drive! (oops) I started it again, but it was running rough and there was a clacking noise in the cylinder. I drove home and it seemed like it was getting worse and worse(the roughness). The car would die if I came to a stop in Drive, but if it was in Park it would idle really rough sometimes would die. After the day I tried to start it again and it would just crank. I took off the cylinder head to discover a nut inside the cylinder. So I put everything back with new gaskets and stuff. I am still having trouble starting the car. I am getting spark to all cylinders and I have new spark plugs. I am getting fuel. I dont know what the problem is now.
