Too Sensitive Accelerator

[dodo]

2009 997.2 C2S

The accelerator is too sensitive almost to an annoying limit. It is particularly too sensitive in the 1500-3000 rpm range. I drove other 997.2s and their accelerators are not that sensitive.

Any suggestion what I can do about this? The dealer tells me it is normal but it is not.

Would replacing the accelerator pedal solve this problem? Or could it be software issue? Are there other hardware we can look at or replace?

Thanks.

Just a thought, is the system not in sports mode? (sport chrono)

[dodo]

no it is not in Sport mode

[RFM]

If it is a non modified DME, i still think on a in sport mode blocked DME at least concerning the pedal/throttle valve function. The DME put no code because he regarded this as normal, anyway this is visible with a PIWIS to compare the pedal possition(s) with the throttle opening(s) values. Probably runs the throttle faster than the pedal like it should be with a car in sport mode.

It might be worth checking the tracks are clean in the throttle body. This is from a 996:

I assume it is the same on a 997. The plastic cover just unclips.

"Sensitive" and "annoying" are subjective terms.

Porsches are known for their immediate responsiveness to all inputs (steering wheel, accelerator etc)

Which is your benchmark?

[dodo]

to Coyot

My benchmark is other 997.2. So I believe something is not right here. I also do not recall it was that sensitive from day one (I have 20K miles on it now)

Thank you all for your responses.

I think the problem may be that the throttle butterfly is dirty. You can try to clean the intake manifold system and look the result.
