Hi Scotty, My 1987 Lincoln Town Car takes a while to start. I’ve changed the spark plugs & the wireset. The only thing left is the distributor cap and rotor. Should I change both, or just the rotor. Anything else you can suggest. I’ve put mostly OEM parts. Should I go OEM or is O’reilly/Autozone parts OK? Thanks,”
OEM is best, and I’d change both the cap and the rotor. BUT, realize that an oldster like that can start hard from both ignition and or fuel problems. If it’s a fuel problem, most guys will live with it rather than spend a small fortune fixing it if the car does eventually start and run ok.
