Anyone else notice when going down the road at one speed with or with out the cruise control the throttle will pulse. Not allot and can't feel it but can hear it and see it doing it on the RPM gauge. I have a 2005 base model.

 

I notice that as well especially when the engine is 'cold' (I'd say within the first 10 mins of my commute). It very rarely does it otherwise. I see it around the 1500 rpm range (+/- 200 rpm). It was worse when the weather was actually cold but has gotten less noticeable lately.

I have no idea why it does it. Thought of asking the dealer about it but it isnt a drastic thing at this point.
