We have a 1990 lincoln lsc mark vii.It runs fine one day, and then it will not start up for 10 to 15 seconds. Then it idles rough and goes from 400 to 900 rpms and then stalls.Plugs,wires, rotor, cap were changed. No vacuum leaks. Added injector cleaner twice, and car still runs good
sometimes then goes bad.Any suggestions would be appreciated.
