Car running rough after spark plugs. Changed on a 2001 Ford Focus

Answers :

There could be too many reasons. Were the plugs gapped\012correctly? Are you sure that the wires are correct in order? If so, the next\012thing you should try is to reset the computer. Sometimes it is possible for the\012computer to read the old spark plug values even if you replace with new ones.\012Reset the computer by disconnecting the battery for 10-15 minutes. The reset\012may cause the computer to take time gathering new spark plug values until few\012duty cycles. I hope this information helps you!
