599 with power loss/limiting

Gentlemen, I would also check the state of charge in your car's batteries. If the battery is somehow not sending adequate voltage, the system would likely act up. The battery acts as a filter for the car's charging system. Battery problems are more likely to be detected when you start up the car.

 

I have mine on a battery tender all the time it's not driving

 

Same for me always on battery tender, and new battery last year.

 

So today all the errors were gone after a hard reset and none of em popped up again. Checked the fuel cap and oil level as specified in the manual - discovered that the oil is overfilled above the max. Tomorrow planning to visit the dealer to get rid of the excessive oil. I guess that was the reason for the Engine Failure light and power loss. Today didnt try to rev to the max due to the oil issue.

 

Well, this evening I did the entire manual technique of checking your oil. After following the procedure to the letter, I found the oil was about 1/4" ABOVE the max line! It was just done by a very reputable Indy Ferrari mechanic before I picked it up after the sale. After reading hundreds of posts in numerous threads, I'm wondering if this could be the problem?
The theory is it gets an oil vapor on the MAF and screws up the mixture readings. It should only do it when you're really romping on it so that might explain why my highway drive home didn't get it all out of whack. I pulled off 570cc of oil and sealed it in a jar, drove around and then final checked it. It's about 90% full between the MIN-MAX line so I think it'll be okay. I'm taking it back to the shop and letting them clean up the MAF and replace the PCV valve. Also, do an OBD check and pull those codes to find out what the blankety blank thing is going on. I'll take that oil in the jar and a funnel checking it along the way as I fill up the car. I'm getting pretty good at it by now.

Getting really frustrating. It took us awhile to tame the 430. I asked my son today if I should've just picked up a used California T. It would be a stretch, but certainly less problems...

Wet sump on the California, so not as difficult to check oil level.

 

Correct - I also wait until the "check ok" message appears and then push the start button. I guess it is the right engine start sequence.
