Idle speed

[butzi65]

Hello to everyone,just a curiosity about the minimum rpm after a cold start (garage temp.20°C - 68°F).

My 3.6 997.1 started near 1200 rpm then, when warm, settles regular idle near 1000 rpm steady.

I remember the last time I drove it (few weeks ago) after a cold start it was near 800 rpm.

What is the right idling speed for a M96.05 engine?

May be my Carrera has a throttle body problem?

Thanks!!!

Yes, likely time to do a good throttle body cleaning and check for leaks.

Thanks Loren,

my idea was to clean the throttle body for the next oil service.

Just a question, can I open the butterfly by my fingers to clean the two sides or I risk to reprogram the e-gas.

I've the intake spray cleaner but I prefer the "finger solution".

I remember it was possible on the first 996 but I don't know if it works on 997.

Yes, just carefully press it open with your fingers. And I highly suggest using a throttle body cleaner - you don't want to damge other parts from the overspray.

So I presume is an urban legend the matter of the reconfiguring of the throttle body settings at the PC, I've the official dealer so far.

I remeber "no touch the throttle butterfly"

Thanks for your kind help

Even if you had to perform a throttle adaption (and I have never had to after cleaning) - you would just disconnect the battery for 5 minutes then turn the ignition key to the "on position" for 1 full minute before touching the gas pedal.
