I just got my p300 a week ago (LOVE IT) it has 700 miles i noticed when i am in park the rpm goes up and down and the car shakes a bit. this was happening every few minutes. Should i be worried.

Thanks

 

How far up and down does the rpm go? Some numbers will be helpful.

 

 

Generally, it is not good idea to rev engine without load into red line for any amount of time. Not good, as in "waited too long to change engine oil" level of not good.

 

 

I re-read OP, and I think you are right. I misread it as "engine shakes when I rev it in neutral'.

To address question, idle should be more or less stable once fully warmed up on any engine. Fluctuating idle is a sign of something not working right, usually vacuum leak somewhere.

 

 

Or just an auxiliary jumping in - I.e. fan, AC, ...? After all, in P every few minutes.
Unless you live somewhere where you need to de-ice windows, I see no reason to leave it running in P for minutes.

 

 

 

Tsar,
I can't see the rpm fluctuating, but my idle (P300) sometimes is 'rougher' then my previous cars with a slight shudder. Sometimes it smooth but never silky smooth. P, R or D doesn't really make a difference. Don't know if that's your same experience?
I'm just waiting to reach 3500 miles to go to the dealer and get that first oil out to ask what their thoughts are. I've not driven any other F-type P300 other then mine so I don't have anything to compare to. (yes, no test ride either I buy cars with my heart lol)

Here is the video. of what happens. Its cold in NYC so if im parked waiting for someone i leave the car on. After about 10 minutes rpms jump on there own. v

Watch the dealer doesn't fleece you if getting it looked at. My dealer contacted me this evening about my first service for my 2.0. €590 , WHAT, for a oil and filter change, we will see if any updates and check other levels he said, my god what are they thinking, going to a specialists car dealer who does other sports cars, he's doing the service, at half the price, genuine parts and booked stamped so all good for warranty.

 

Anyone had a chance t look at the video?

Yes, I have, and that variation in rpm is not normal.

 

 

how hard is a vacuum leak to fix? can they do it while i wait?

 

Forgive me if I’m missing something but its new so shouldn’t the dealer fix it under warranty?

 

 

I picked up my p300 last month and have experienced the same thing, it only does it sometimes. It doesn't feel normal but I guess it may be.
