I have a 99 superduty with a build date in 98.

What differences and problems should I be aware of. This is a 6 speed and it's acting a little goofy. I'm thinking it has a dead injector was wondering what would be the way to test for it.

thanks,
Doug

You have an early 99 PSD

You could do a buzz test but you need to find a shop with the proper scanner.
