    Hi all, I had that experienced the same cold die out issue with my old lady years ago. We found it to be one leaky injector. After we replaced all the injectors with brass, problem solved. FYI, you can purchase Bosch injectors for $40 instead of Ferrari labeled for $400 each.

    I have new injectors on hand as well. Bosch brass ones at $20/ea through a seller on Amazon. I’m going to replace the wires first though.

    before you change the injectors, you can prop on the exhaust manifold per cylinder and take a reading. Also, the Bosch injectors have to be seated and bleed properly before you install them.

    I’ve not seen any instruction about seating and bleeding the fuel injectors in the WSM. Can you explain further?

    When I had the injectors replaced, it was done my the dealer and the tech had a special tool on a bench that he pressed each injector to bleed and then installed them. Not sure why it was done that way. I watched him doing it.

    Don't think they were "bleeding" the injector, if you read the WSM pages D49-51 there is a great description of testing the injectors using a special tool that measures opening pressure, leakage, spray pattern etc. When I was setting up my fuel injection system after having my fuel distributors rebuilt by CIS Flowtech, I had two terrible injectors where the spray pattern was not as it should have been ie Fig 39 A in the WSM. I bought 15 new injectors when I replace mine just to have a few extras and two of the new injectors had terrible spray patterns. You really need to know what the fuel pressure is, are the lines clean? are you getting the right delivery to the injector? Replacing the injectors isn't a difficult job but there are other things to look at if properly servicing the fuel injection system. Good luck.

    as jeff has written: not bleeding, testing the spray pattern and the pressure
    also after testing your mechanic opened the line again? so air coming in again. those injectors getting bleeded automatically when working,

    The bleed was done before the install on a bench press tool of some kind. Once injectors were installed on the car, it was never re-opened. I don't know what the tool was called but very similar to Jeff's post.

    Jeff's post is more accurate description of what I was trying to describe. Sorry for the confusion.

    Thanks to those who work on their cars and posted the correct information from actual experience. It can be confusing navigating through wrong info.

    I’m going to replace my spark wires first and see how things go, then replace the injectors when I have more time.

    Hi All-

    Spark wires, spark plugs, and spark plug extension have all been replaced with parts from GT Car Parts of Arizona. Price was pretty decent for all of the parts. I ohmed out the wires after connecting them to the distributor cap and the results were very consistent and SIGNIFICANTLY lower than the readings I was getting with the old wires.

    All plugs were torqued to spec, spark wires were silicone greased where the boot meets the extension, and the distributor points were cleaned up.

    Car started right up and idled rock steady. Pulled smoother and stronger than ever before. I didn't have time to do any more than about 5 miles but so far I think logic and experience say I have it fixed. I'll know tomorrow when I take it on a longer ride. Usually about ten miles is enough to get it to act the way it was.

    Woohoo!

    Thank you! Hope this is it. We will see. The right bank ohm'd out exactly how I would have expected it to. The left bank wasn't as perfect but compared to original it was pretty spectacular. These are the $250/side wires that one can buy from Ferr Parts or GT Car Parts. They ship from Italy and are hundreds of dollars cheaper than Ferrari labeled parts. Readings pictured below:

    Yeah wires, caps and rotors do make big difference. On my old english cars it was beer money on ferraris it's Chateau Lafite Rothschild.
