Slow Down Light?

Hey guys, I'm new to the forums and the Ferrari world
I have what I think a "little problem?"..
I bought a 02 Ferrari 360 M6 tranny, it has the Tubi exhaust.. Every time I drive for lets say 11 miles a light on the dash keeps flashing and keep telling me "Slow Down" and I think it's the O2 sensor correct?
Well.. Today I took the car for a little drive, started it and the exhaust sound is a little bit strange? Well it's actually rough! I drove it for like 300 meters away from home and the RPM dropped to 0 then to normal which I think is 1k? Sorry I had two Corvettes before and this is my first Ferrari so just keep going with me
Car feels like it's "Pushing itself" and "Kindda" Slow! not kindda, to be honest VERY! so I parked it for 20 minutes and fired up the engine again and the slow down is still there which is OK but it felt a little bit better.. Less roughness, softer and smoother.. I repeat, LESS not VERY
Thanks all!

I'm getting the Slow Down light right, too, as a result of the fact that my ECU's were flashed by EVO on behalf of fabspeed for headers without air rails which we subsequently replaced with a set that instead had air rails. The ECU's are off directly to EVO for reflashing again. I have no idea if the Tubi upgrade requires an ECU flash to avoid CEL and Slow Down, but putting it out there.

Thanks for the pic buddy..
I hope it's nothing serious? So I'm getting this message because I have a bad/broken o2 sensor that's all?
Much appreciated

P.S.: As I said before, I am sorry for the dump questions! I only had the car for two days

Do you have a check engine code?
Big part of the time when the sensors are bad it may through a code.

Yes I do.
The seller told me it's because the car has the Tubi and he didn't re-flash the ECU, I drove it before I buy it.. It was very smooth.
Also when I bought it, first day was just fine then this
I told him about the slow down thingie.. He told me to replace the o2 sensor because it's broken.

Can you check what is the code. Use a regular OBD2 scaner to get it.

This could be serious.

The S L O W D O W N light came on after I filled up the car with gas on my way to the dealer for service. I drove with the light on for about 10 miles.

Told them to check into this. Apparently a sensor on one of the cylinder banks was bad (keeps the banks synchronized). They could not start the car after I left.

So get it checked out. Hope yours is minor.

@Ingpr:
Sorry I don't have one right now.

@PhilNotHill:
I'm taking the car to the dealer on Sunday. Hope it's just a bad o2 sensor and nothing serious!

Update: I took my car from the dealer. They changed the exhaust plug/ecu (Passenger side, they said it's the one causing the SDL) (I really don't know the exact name of this very part because I lost the receipet sorry!
Bottom line.. Everything was OK, they even drove the car for nearly 2 KM and called me and they said "Hello sir, we have tested your Ferrari and we are happy to inform you that your car is ready", so I took the car for a test drive for like 30 KM (I was heading back home) then the damn thing started to flash AGAIN!!! Slow down, slow down then dissapeared! I was like "Oh.. Thank you lord" continued my journey to home then slow down, slow down, slow down! I took my foot of the gas pedal, drove it on a 80 KM/H same! 70? Same WTH? 60!! Same! parked it and let it cool for like 45 mintues and gave it a shot slow down again! COME ON!! Any thoughts guys?

P.S.: It's not a still SDL, it is flashing.

Thanks!

Did you try to disconnect the batt (using the switch in the trunk); let the car cool down for maybe 1 hr; reconnect the batt; start and idling for 15 mins - then drive to see what happens?

I had/have a similar problem. Most likely it is the other exhaust sensor ECU. Yes, there are two, one for each bank. You had one changed and the problem went away only to return, so i would change the other one before doing anything else. If not that, then you may need to change one or both thermocouples. But if it's not throwing a hard overheat code then most likely your problem is the sensor ECU. Good luck and be sure to post results.

I have the exact same problem Alpha...including the one time where it felt completely dead and had to "limp" home...I had the Pyrometer and Controller changed in September as it was showing an incorrect high temperature, they test drove it and said it was fine (and I trust them), then I get it home and (of course) the light came on again.

In fact, I can almost always get it to come on - always when the car is clearly not too hot...following the same procedure:

1. Start car, let idle for 3-5 minutes
2. Take off, shifting from 1st to 3rd (since it's a little too cold to go into 2nd right away)
3. In 3rd, about 400 yards from home: SLOW DOWN, for 7-10 seconds
4. Most of the time, that's it - never see it again (this is after the pyro fix)
5. The one time the RPMs died on me, it was coupled with a CEL

Told the shop let's revisit in the Spring

Running rough.. hmmm... had my slow down light start flashing during a drive 2 weeks ago. Drop in power up a highway bridge, etc etc. kept flashing. Got home (couple of min, <1mile) and the right cat was glowing.. any of the exhaust glowing?

Reason I ask.. the rough running in my car was due to a couple of crappy coils, that resulted in gas getting into the exhaust, causing temperatures getting too hot in the cat.. thus the slow down light and the drop in power.

Did they check the coils? Mine did not give the code off to the reader. In my case, my mechanic pulled the spark plugs and we deduced two did not look right.. the same two had bad coils. Replaced and now she's perfect. :-)

Wishing best of luck!

BTW if the headers are stock, precat might be on my thoughts as well if present.. hope it's not and I hope I'm off base 180% on both of these thoughts.. !
