Throttle Jumpy

[KRZTACO]

I have a 2000 Boxster S with 42,000 miles, here's the deal:

--When shifting from 1-2, or 3-4, etc my throttle blips up a few hundred RPM once I disengage the clutch and start going into the next hear up.

--When in nuetral and I step on the gas a little bit, its almost like the throttle gets stuck a little and over-revs (nothing dangerous but it should stop revving once the pedal is lifted).

--No CEL

Nothing serious, however its is beginning to get a little worse over the past 10,000 miles.

MAF?, dirty Vac hose somewhere??

Any help is much appreciated.

Is it all the time or just when cold, hot or warming up?

Sounds like the MAF, O2 sensor or vacuum leak. You can try plugging in an OBDII reader that will record the outputs and resistance of sensors and see if anything is strange. That may help in figuring out which it is.

I have it narrowed down to the following:

--IACV
--Throttle housing

Hi,

Excuse my ignorance, but isn't the 2.7 Drive by Wire? If so, couldn't it also be a Software issue?
