The vacuum leak detected is really minor. On my vehicle I saw no change in performance. But that was back then. Now with 120k miles on it, it's not as peppy as it once was.
Make sure all your vacuum hoses and tubes are in good repair. Pay special attention to the PVC and its tube and end fittings.

thanks again for replying. I just bought the van 2 weeks ago. It drove fine the 1st week., then a little stutter at hwy speeds and now it feels a little sluggish and sometimes stalls on me. I realize that there could be so many reasons for this and I will read the threads like crazy. 171 and 174 come up so i thought i"ll start there and do the tsb procedure. will check fuel pressure and all vacuum lines and etc and hopefully resolve this. Have u heard of the tsb repair fixing stalling or sluggish motors?. If it only kills the cel codes 171,174, then perhaps i should work on the stalling problem 1st. cheers
