How do I fix crossed spark plug wires on a 1989 grand marquis.
By "crossed" do you mean they were installed improperly? If so, find the correct firing order, remove the wires and reinstall them correctly.
Your firing order should be 1-5-4-2-6-3-7-8. What do you currently have and any idea who/how the wires got changed?
