Had the CEL light up today in my 2004 360 Spider and the car lost a lot of power. Exhaust smells rich. Limped back home. OBDII says misfires in multiple cylinders (8,6,5,7). I will be taking it to my mechanic next week for a look see. Is this a bad ignition coil? Any ideas?
You may not have the same problem that is causing your miss fire codes. But one of the area to check would be under the right side MAF, for whatever reason when Ferrari constructed the 360 spider the solenoid brackets assembly rubs on a line that connects between the two MAFs right in front of the intake manifold. It is most retarded thing I have ever seen, I first thought this was just on my spider then saw this on several other spiders. The bracket for the solenoid actually rubs on the aluminum line and from the engine vibration it eventually cuts the hard aluminum line and creates a huge vaccum leak. Needless to say I forked out my own money for their mistake and replaced the aluminum line with a huge gash in it. Image Unavailable, Please Login
Thanks for the advice. I checked the location of the vacuum line between the two MAF's and it has been relocated on my car, a 2004, closer to the manifolds. So, I guess Ferrari figured out the vibration damage effect and moved the line out of harms way. So, it is possible that one faulty plug can cause misfiles in multiple cylinders?
One bad plug would typically cause that cylinder to mis-fire. Do you have an entire bank dead? If that is the case I would look for something affecting the entire bank, and not something cylinder specific. Jes
Thanks, I thought they were numbered even on one side and odd on the other. So, do you think this is an ignition problem or a fuel problem?
Idle is a little low, maybe about 900 RPM's, and the car has almost no torque/pick-up when the accelerator is pressed, very slow to pull away. Any ideas?
Can be one or the other but I would concentrate on something which is common to all the cylinders of bank 2: MAF, air leak, connectors, .... Have you connected an OBD2 reader to your car? If yes, what are the values of the Long Term Fuel Trims (LTFT)? It could give some insights on the injection operation and if it tries to compensate some defaults ....
It could be intake manifold gaskets. Try spraying some water with a spray bottle at the base of the manifold and see if that affects your idle.
Thanks for the all the advice. I am taking the car to my mechanic for OBD interrogation this week and I will post the results.
could be a bad MAF sensor. I have seen 360's idle so abruptly i thought the engine mounts were going to be ripped from the frame and other 360's would drop a bank and have a loss of power. Another reason why one side of the bank would drop is do to the thermocouples telling the ecu that the cat is getting too hot for that side. Most of the time its a small box that the thermocouple is attached to that fails.
Took her to the hospital today. Very sick, just made it there. Mechanic said "she doesn't have the power to take skin off rice pudding" (you have to be British to get it). OBD says: multiple misfires, left bank; oxygen sensor dead; oil pressure sending unit dead. More to come, I'll post follow up as the drama unfolds.
I would be surprised if OBDII reports bad oil pressure sender, but I have been surprised before... Best of luck, fingers crossed for a quick recovery, Jes
I have a multiple misfire on cylinder 4 & 6. Car working fine on high rpm but not on low rpm. Have order 2 spark plugs and 2 coils to try to replace those on these cylinders as a start. If this not work, then I have to order a truck and send the car to the workshop ( 7 hrs drive Wonder where cylinder 4 and 6 is located if you facing forward from the engine compartment ? I am not intending to do the job and maybe the local mechanic now, but ask just to be on the safe side.
Hi Eric! My cheapo obd2 reader does not read LTFT. I did not know that generic units could read that. Do you know of readers that are more sofistocted and is the bulk of LTFT type data called something so I can find a testor that will read that info? Most testor packaging is pretty sketchy. Thanks!
Hi Carl, Lont Term and Short Term Fuel Trim (LTFT & STFT) are part of the generic OBD2 data and so, they are readable by any reader ... provided it asks the ECU to send the data. I have never used any autonomous reader, I always connect my car to my laptop or my PDA with different softwares. I never had any problem to read the LTFT and STFT on my 355. I think that all the readers which are able to display live data (PIDs), and not only DTC, should read the fuel trim data. You should find some potential candidates on the following link. Equus 3130 seems to be one of them ... http://www.youtube.com/watch?v=aibRCA8oPOo&feature=related
Mechanic can't figure it out after two weeks. Tried replacing O2 sensors, cleaned MAPs. May have to take it to the dealer. Any theories would be appreciated
Our current theory is a crack/leak in left exhaust manifold causing exhaust gas reversion and the O2 sensor to send a too lean signal to left bank ECU which in turn produces an over rich mixture leading to the misfires and "glowing red" left cat. Thermo couple senses cat temp over limit and produces "SLOW DOWN" flash to anunciator. It makes sense, but please let me know if you have any other theories. Thanks
It makes sense to me, too. Have mechanic do a smoke test to see if the manifolds are leaking. It's the only way to tell w/o removing the manifolds, as they are shrouded in insulating material so you can't see everything.
