Low RPM's no power... but it idles.

After having some wonderful trouble free canyon rides to the ocean I noticed a recent problem while getting ready for my Sunday ride.After warm-up the RPM's at idle were around 800 normally its around 1000 and the power wasn't there when I accelerate. Sadly I had to stay home but now I am wondering what the problem or should I say how much the problem is going to be.... damn looks like I will have to drive something else tomorrow... my 53 Chevy truck or the Porsche hmmmmm......

I have a 328 and you might as well check what everyone told me to check, the spark plug extenders. Symptoms are a little different than what I had but worth looking. See my post in the 328 section along with pics.

Addressing symptoms is everything.

She is warming up right now and after a few minutes I am getting hot exhaust on both sides. The RPM range is still around 800 doesn't sound like its missing, no smoke, Starts right up just doesn't have power when I put it in gear it stalls as soon as I release the clutch... it would normally move forward with all the torque these things have... noticed this problem once before then it just cleared up. almost like not enough gas is going into the engine.

The exhaust mixes in the muffler. The exhaust temp at the tail pipe means little.

Exhaust temp needs to be measured pre muffler.

Is this part of the 512's two fuel pump system probelm where one may go out and the other takes up the load?

Inferring that from the recent Forza buyer’s guide and one of your and another owner’s comments.

Not really. Few engine management systems or components exist for 12 cylinder engines so Ferrari has traditionally chosen to treat their 12's as a pair of 6's. 2 everything. When something quits it leaves half of the motor running. It is not meant in any way to create redundancy.


I don't really know what you mean fuel pump problem?

ah. Perhaps better said as 'not a problem' but more a characteristic. What the one user mentioned was [don't have the copy here] para...."....the only problem I had was a lack of power due to one of the fuel pumps giving out, where I wasn't stranded, just limping..."

I'll need to choose words more carefully. From what everyone who owned stated, they all had high praise for reliability.

Was the relay actually defective or was there a loose/corroded connection?
