Ferrari Mailing List: Re: 512TR Check Engine Light (1-6)

[Peter Rychel (dino308gt4]

When my friend had his ’94 348 Spider, he had the sticky issue and was told to wipe down the items with brake fluid. He did just that and it removed the residue easily.

 

Ferrari and other manufacturers use this rubber coating/substance that over time, when exposed long enough to the atmosphere, the oils and other petroleum products in it react and breakdown, leaching out from whatever binder or substrate that coats the surfaces. I had a food vacuum sealer that was coated with the same stuff and yep, it became sticky too after time. I did the same trick and now it’s just the bare black plastic. Thing is, the machine still works well and I wasn’t going to throw it out for cosmetic reasons.

 

As for the O2 sensor, check to see how it’s connected to the ECU. On my ’89 Mondial, it each plugs into a device which is then plugged into the ECU. I don’t what these are (maybe an amplifier or a signal converter?), but that can cause a problem and not just the sensor itself:

Did all your other gauges look OK?  temp, pressures, etc...

 

If so, yeah.  Unless the 02 sensor was significantly out of whack and blew a bunch of fuel through the motor (cylinder washdown, cats glowing red) or was extremely lean... but I think you would have noticed those issues by the sound/power of the motor or the gauges.

 

FWIW...  Sticky.... The hand grips/joy sticks on my excavator started getting sticky, like the Ferrari interiors have been known to do.   A guy at the heavy equipment shop told me to spray them with Bug and Tar Remover from Turtle Wax then scrub them with a stiff bristle brush.  He showed me a set that looked great.   I haven't done it yet because I keep having to use the damn excavator...  So once I get to a point I know I don't have to move or dig anything I'll give it a try.  It that fails, I've got a friend who thinks he can get them scanned and 3D printed.

All,

 

Just as arriving home this morning from a relatively gentle drive (highways) of an hour or two, check engine light lit. Most likely cause O2 sensor? I'm due for annual inspection anyway, so will certainly have mechanics troubleshoot -- but am I correct that low risk of significant damage that might result from driving it about 10 miles despite check engine light?

 

Thanks,

Larry

 

P.S. Also extremely to find that now another piece of my black center console is deteriorating -- becoming disgustingly sticky, probably due to temperature and humidity in my garage. Not about to buy expensive carbon fiber replacement trim.
