Lets play a game: Name all the possible causes of a "cylinder misfire"

[jimmyducati]

Here is the latest log I recorded this morning on my way into work. I let it record for a couple minutes, during this time I accelerated aggressively and as usual it misfired. I included all of the PID's in torque that looked like they could help with the problem, but the misfire pid wasn't active unfortunately. Does anyone have a misfire pid that has been written for the ecoboost?

I'm pretty sure there are "misfire event" & "misfire trips" gauges figured out...maybe on the 1st page of the thread "torque pids take 2"

There is a misfire widget built into torque.

Scroll down 👇 when selecting gauges and you should see it.

Iirc mode 06 data shows them as well.

STFTs look out of whack, Jimmy, possibly trying to compensate for inadequate fuel flow.

No O2 data?  That is surprising!  I assume the car was warmed up before the WOT runs?

Misfire counts are listed as "Cylinder X Misfire Count" and "Total Number of Misfires" in the Add Sensor list.  You can also monitor Current Drive Cycle Status as a display in Torque.  This, along with Emissions Monitors is listed directly under the Select Type of Display list.

Much easier to see Mode 06 data in OBDLink software, unfortunately only works with OBDLink hardware tho.

Ill look for those PID's this afternoon, Ill include them in the next log, but I'm not sure its going to be necessary. I just pulled a couple of new codes when I got back to the office, Bank 2 sensor 1 O2 sensor is out of limits and the Bank 2 Catalytic converter is also reading as bad.. That explains why the O2 data was missing in parts of the graph and could explain why the fuel was out of whack at times. Both a symptom of excess fuel being shoved through the exhaust, so it kinda confirms fuel injector suspicions. Im probably going to pay the 25$ to get the year subscription to chiltons online (unless someone has a SHO maintenance manual on digits) so I can pull the injector and have it either tested or replaced...

I guess now Im in the market for a set of catless DP's... great way to get a performance part is to justify it to the woman that the part needs to be replaced anyway!!
