Need a little help

[Bluewater Man]

Hey Guys:

Thanks again for the help with my vibration problems! On to new problems...

Again I have a 1993 FSB with 351 efi. The truck runs pretty good but has some hesitation on the accel and will tend to sputter when you let off the gas. Also the idle seems a bit high at approx 1000 rpms.

Where should I start looking?

Thanks in advance

Gene
