I replaced my valve cover gasket a week ago, and after I put everything back together I messed up on the order of the spark plug wires. Before I put the spark plug wires in the correct order I was having engine difficulty. The car would start but the idle was not smooth, it was jerking. Once I placed the spaark plug wires in the correct order it seemed fine. Until it began to jerk again once I started it. After it began to idle at 1,000 rpm it seemed fine. I let it warm up and put it in first gear, it would speed up fine but once I put it into second gear it would hesitate but it would speed up fine until I got around 3,000 rpm and the engine began to go in a bucking motion. The Service Engine Soon light came on once it began to buck. What can be the problem? Thank you for your help.
