California 2010 burning to much gas?

Half a tank in 60 miles is not normal, and it should not run rough like you describe.

How many miles are on the car?

 

I’d pin the blame on one obvious culprit: the fuel sensor inside the tank feeding false information. That fuel consumption you reported, burning half a tank of gas in 60mi, would only be possible imvho if you went all 60mi at full throttle/top speed.

Rough/Rich idle may be another entirely different issue.

For peace of mind, I’d recommend a visit to the nearest official dealer. In any case, I think it’ll be an easy fix.

Kind regards,

Nuno.

 

Who did you buy the car from? Did you request to see the entire service history of the car before buying it? When was it last serviced? Did you have the car certified by a dealer or at least do a PPI as a condition of purchase?

To be honest, if your account of events is accurate, your car may be in serious need of a tune up. If I were you I would have it checked by a Ferrari dealer before using it further.

 

Joseph,

If it’s under warranty, you’ll be fine. Warranties matter, namely if you bought the car outside the Ferrari official dealer network.

Once they’ve figured it out, please let us know what the problem was. If this happened back in the day, I’d say your carburetors needed a serious tune!

Kind regards,

Nuno.

 

Two issues.

I don’t recall when Ferrari started providing the 7 year free annual service with the Cali but even if your 2010 car came with that free service it would have run out in 2017 at the latest. If your car has a tuneup issue it may be because the previous owner decided to neglect the servicing knowing that he would get rid of the car once it starts to act up. Some people are cold blooded like that. They will “use up” an asset and then try to palm off the needed servicing on someone else. You see this a lot especially with neglected or even trashed real estate properties.

Be careful because this has a bearing on any warranty.

A badly tuned car will poison and destroy its catalytic converters very quickly. So do not drive the car at all until the dealer figures out what’s wrong with it. Catalytic converters are wear and tear items and I believe they are not covered by any warranty. They would also be pretty expensive parts to replace. You will also see other issues when the cats stop working properly so you may still be okay but I would stop driving the car for now. If you hear clunking noises from below and experience jerky acceleration those are signs of failure of the cats and you should immediately contact the dealer and the seller.

 

Mine is a 2014 with HS and in just normal spirited driving around town it does seem to use quite a bit of gas, but I am not that concerned because I didn't buy it for its fuel economy. However, we did take it on an extended trip last week and to my surprise it got the manufacturer claimed 19 MPG on 2 sequential full tanks.

 

These cars are indeed thirsty, but 7 mpg is way off. Not even sure I could spank an 812 into those numbers on a track if I tried.

The combination of rough idle and poor fuel consumption goes hand in hand. I'm thinking bad o2 sensor or perhaps a leak in the exhaust upstream from the o2 sensor. This will also lead to false readings.

 

I keep a track of the km and the bills, so it is easy to correlate.

Based on the data of last ~1200 km from my California T HS, I get 22 liters per 100 km. That's 10.7 mpg.

No track use. Needless to say i use manual mostly.

 

lnteresting and I am glad you got a replacement but do make sure you have the full service records and that the dealer certifies the car (same as PPI). A warranty of at least 1 year would be best to have. However, I do find it shocking that they would sell a car in that condition.

FWIW, with 2 cylinders not firing, all the unburnt gas will poison the catalytic converter(s) and destroy them very quickly if the car is driven for any amount of time. Once the cats are destroyed the car is undriveable. The cause for the non firing cylinders can also be very problematic.

Good luck with the replacement car and make sure it’s properly serviced.

 

What do you mean by only 6 blocks were igniting? What is a "block"?

Only blocks I know of are engine blocks. There's one per engine and they don't ignite.

 

The engine mounts replacement will cure a lot of the shaking. Mine shook like a wet dog until I got those done. Unfortunately the warranty doesn't cover them.

 

Unfortunately, most people are quite naïve about insurance and warranties, live under a false sense of security. You have to carefully read the policies to see what they actually cover. Everything else not mentioned or specifically excluded ARE NOT COVERED.

For instance, the Ferrari NewPower warranty specifically states:

The New Power extended warranty covers the following components:
• engine;
• transmission;
• suspension;
• steering;
• electrical system.
​

Nothing else is covered under that policy. In addition, if you continue to read the document, it then states that for these items, oil seals, oil leaks, leaks, some valves and pumps are also NOT COVERED. However, in a sense that's actually fair, because those are considered wear and tear items as they are not expected to last the life of the car. And if they were covered, some people would forego regular maintenance and wait for those parts to fail and use their warranties to cover them. It would encourage some people to not service their cars after the free maintenance period expires. There are a lot of people like that.

As for the engine mounts, I consider them a design flaw but I may be wrong. At any rate, the factory would have to do a recall for them to be covered.

At any rate, the problem that the OP of this thread experienced was apparently not caused by failed engine mounts, even though I have stated before that every Cali owner should have their original mounts replaced as a preventive measure and also to improve the functioning (handling) of the car.
