360 modena spark issues

So this is what I gather:
- Told to "Slow Down" and turned out to be a bad coil pack (sounds about right)
- Sprayed down engine and then shorted things and then ran crappy until it did not run at all
- Took it to "a shop" and they replaced all the coil packs afterwhich it ran?
- Still don't have spark in 5+7 after all this?

Who is this Shop? Do they service FCars or are they a bimmer/Porsche/ Meinecke shop?
My experience is the ECU's are pretty robust, it's usually a sensor or bad wiring in the loom. Intuitively, if the ECU for a bad goes bad.. I'd expect all the plugs in that bank not to fire. not just 1 or 2. Did they test the connector at the coil for voltage?

Did they replace all the spark plugs as well? If 5+7 have a fouled plug, you're replacing the coil but still have a crappy plug. Were you spraying water near the air intake? If your gaskets are bad you could be getting some water or air into the cylinder affecting combustion.

Coils are a common issue, esp. after you pressure wash the engine bay or use engine degreaser. Some other cars may have issues with the ECU.. but I don't think its that common.. they are located under the engine cover panel on each side of the engine FYI.

So he didn't rreset it and let it relearn. Do it again and see where you stand. What's wrong with it now?

 

I would plug in a scanner and check if there is a pending code.

 

The quality and quantity of help you receive on FChat is a direct reflection of the quality and quantity of information provided regarding the issue. I am recommending you take a little time and outline the issue, order of events, CE codes (if any), etc.

 

A couple shops just over the boarder in MA with an OB2 and experience to help you sort things out before winter comes. Think of bringing to another shop?

 

It's time. When things get like this you might just need to bring it in to someone that has a proper SD2 or Leonardo scanner.

I wonder if it's ignition or fuel mixture... Replace the plugs and take pics of how the tips look and paste them here. The tips should be nice and white ash.

Any OBD2 scanner codes? Any check engine light? I can't imagine its running like this and not giving you a code at least as a result of the running..

 

I know on other vehicles, if you wash the engine and cause spark issues the plugs WILL be fouled and have to be cleaned or replaced. I've seen this on other non Ferrari engines. BMW, Miata, etc... Cheapest and easiest first pass fix.

 

What shop was it? Your in my neck of the woods.

I would bring the car up to AMNE or IFS. Both are less than 2 hours from you.

 

There are inexpensive spark testers you could insert inline between the coil pack and the spark plug to see the spark with your eyes. Get a few of these, connect to the coils/plugs in question and see for yourself.

P1632: CAN-interface: Timeout Electronic Clutch (KUP): Bank 2

Check CAN line
Check CAN impedance= 60 ohms
Check marelli F1 ecu error.

Now you know the issue is with bank 2. CAN bus is the communications line that the ECU uses to communicate with the various components in the car.

Sounds like there is an issue with the connection possibly to the F1 transmission ECU. There are a million connections and interconnections on the electronics in the car. Try taking off the panel behind the passenger seat. The big electronic box there is the F1 ECU. try reseating the connections. Otherwise, consider a short in the wiring loom giving you this error. A SCAN WITH AN SD2 is NOT A BAD IDEA! Might be some codes not showing on the OBD2..

 

Do yourself a favor and take the car to Ferrari New England. Everyone is scared of dealers, but these guys are good. I am in RI also and have a 360. They have worked on my car since day one, and reviewing the records they have fixed a variety of issues quickly and reasonably. If anyone has seen your problem before, it's them.

 

Exactly the reason to never power wash an engine!

 

When it's an issue like this, there is some hunting that required. Better tools like the scanner can help isolate things like any wiring issues faster than you can do it on your own in the garage.

Just watch out that they don't give you the line... "well lets just replace the engine wiring loom and see where that goes". YOU could do that. They should give you some better clue isolating the problem, and then take it from there.

 

Crank position sensor might shut down that bank....

 

Please update us when the problem is resolved

I work about a half mile from IFS and I have visited a few times, great place!

 

Yikes!!!

How exactly does a belt get shredded???

I hope some chimes with an answer!!!
