any of you have had problems with misfire detection and diagnosis did not detect the error?

 

Nope, but I use Mercedes' diagnostic's system. I have however had a "cheap" (relative in respects to DAS) $100 walmart scanner not detect quite a few codes before.

 

so you're telling me that it is possible there is a misfire and that this is not detected by the OBD? do you know if the SRT6 is a problem that often misfire?

 

It has to be consistent to throw a light, and there has to be a light for your dime-a-dozen scanners to pick something up. If you're misfiring and you are sure about it I would check the MAF, Crank angle sensor, cam position sensor, and vacuum lines, in that order.

 

is a bosch obd, the carryover to tomorrow bosch car service them fail to see the error, tell me what I should do in order to control? seeks to specify well because they are Italian and it might be difficult to translate

 

Josh is saying :
1. Replace the MAF sensor. ( Mass Air Flow sensor )
If that does not resolve the issue, then
2. replace the CPS ( Crankshaft Position Sensor )
If that does not resolve the issue, then
3. replace the Camshaft Position Sensor.
If that does not resolve the issue, then
4. Use some method that detects vacuum leaks to ensure none exists.
One method is to use an UNLIT propane torch and pass it close to any suspected source of leak, if the engine smooths out, you found the leak.
BE VERY CAREFUL WITH THIS, AS YOU ARE INTRODUCING AN EXPLOSIVE ELEMENT INTO AN AREA WHERE SPARKS MIGHT EXIST !!!!!!!!

I disclaim any responsibility if you or the mechanic chooses to use this method.

 

Thanks George. ^^^^^^^^ There's the answer

 

so most of the parts to be inspected and possibly replaced all sensors are not mechanical parts?

 

The MAF is a plastic thing attached with 2 screws.
The CPS is also a plastic part attached with one screw.
The Camshaft Position Sensor also is plastic, attached with one screw.

All 3 have an electrical connector.

Thank you very much tomorrow I will give this information to the bosch car service, if you have any other tips let me know thanks

 

this is the problem, it seems only a misfire that almost always happens when the car is stopped one or two days sometimes happened after a week of detention and almost never with car in motion a couple of times, this problem does not appear to diagnosis bosch

 

Holy ****! That is something serious. I'm sorry but I have no experience with something like that. That is NOT a misfire.

 

Just a correction. A srt-6 does not have a MAF, only the regular crossfires have one.

 

N/A's? True. He never specified model so I assumed.
