360: Red hot exhaust

Evening all
Been out of the country for about a month and took the 360 out for its first spin in at least 6 weeks today. All going well until the "Slow Down" warning message started flashing at me every time I went over about 6,000 revs. It would then disappear as soon as I dropped below about 5,000 rpm.

A little while later the "Check Engine" warning light appears (in orange) and stays on. So I cut the spin short went home and reversed into the garage.

I popped the engine lid - but could not even open it because it was so hot to touch. In the end I opened it with an oven glove! A small bit of paint on the rear bumper had even started to bubble with the heat. Never seen anything like it.

Anyone ever had a similar experience or suggest what might have caused this incredible heat. 2 hours later its still ticking from the heat.

Incidentally the 360 has an exhaust fabricated by Nick Cartwright (the Ferrari independant) I bought it from, no cats in it (I think).

Cheers....

Exhaust system

It's pretty hard to diagnose over the internet but it sounds very much like serious issue(s) with your exhaust system. My first guess (emphasis on "guess") would probably be the exhaust system failing to communicate correctly with the engine ECUs (e.g., bad O2 sensor or improperly connected, etc.) possibly causing overly rich mixture resulting in excessive exhaust temperatures. I would hope you get the car to an expert ASAP with minimal driving as the condition you are describing can be *very* dangerous because of the risk of fire.

Good luck and please let us know what you find out.

Quick update on the above.

Had the 360 plugged in to the Ferrari software at a local independent specialist today and the faults read. Turns out the first O2 sensor on the left bank of the engine/exhaust was reading an error (apparently this caused the "check engine" light) and the temperature probe on the same side was reading high temps (and this caused the "slow down" warning).

A bit of further investigation uncovered that the guys think that cylinder no. 6 is not firing at all. They put in a new coil but this did not resolve the problem. So the car will be going back there mid next week for some more work to try to find the fault and to get a service done at the same time.

In the meantime if anyone has any ideas as to what the cause might be, or why cylinder 6 might not be functioning I would be glad to hear it.

Final installment. Happy ending. Turns out the misfire was nothing more sinister than a loose electrical connection. My baby is back from the garage, with a minor service done as well and 8 new spark plugs. Sounds the way is should again and is driving beautifully. Now, if I could just arrange a little bit of sunshine...

good news. I was about to ask about the recirc canister as 3 & 6 can be a problem as it wears out.

BUT, my more important question is: was the SLOW DOWN light red or amber at the time.
