Hesitation and uneven throttle

[ikarma]

Hi all,

I hate to go in blind so just a quick note before I take my Boxster to the dealer.

I have a 2000 with approx 45K and lately it is experiencing hesitation through 1st and 2nd gears. It seems I can't keep an even 1500 rpm, when I press the pedal to 1500 rpm and keep my foot steady it will suddenly dip to 800 then rise again to 1500, dip then rise etc.... I'm a newby to the Boxster world and am just now learning about the dreaded MAF, o2 sensors etc. I just hope this issue is a minor one.

Any thoughts on my problem would be appreciated.
