Did you ever fix this issue? I am having a somewhat similar issue where i can take a drive and it runs great, or it will misfire at a light and i will get cam codes. Completely random and have no clue what to do.
Also completely forgot a possible important detail. After the install i drove it for a week or so completely fine, no issues. The thing is, i have a constant evap code from charcoal canister delete so i have no clue if those codes came up before the issues started. Week ish after install car...
Heres 3 logs with the parameters you mentioned, hopefully at least one gives some insight. During this drive, the misfires got pretty bad and car almost died at one point. Every time they go into failsafe, i need to turn the car off and on to get readings to come up again.
Its definitely interesting how both exhaust cams do that now that you point it out, after work today I will definitely take a log using just those parameters.
Was able to get a log in forscan of the issue happening, i did basic pidās then pretty much everything with cam degree attached to it for as much data as possible. The log starts off idling fine at a light and as i start cruising, i can feel it misfiring and then at some point it goes into that...
Makes sense, tomorrow I will have my coworker look at it with his snap-on scanner which should be able to look at all that data which my logging software cannot.
Just did a wiggle test on that sensors wiring, nothing at all. But i do have a theory in my head that makes sense to me at least. Since pac 1234x springs have significantly higher seat pressure (92lbs vs 67lbs from stock). Could it be possible that vct is having a hard time controlling cams...
It is entirely possible that i pulled a wire too hard though, it isnāt easy to take off the Christmas tree pins on the valve cover and i could have damaged something, just odd that it only happens at idle after rolling stop 90% of the time it misfires.
Makes perfect sense, i though they were being put in some sort of fail safe the way all of them reacted in unison. I use sct livelink to datalog and a desired exhaust cam pid doesnāt show up for some reason, but now i am thinking that the phaser for the cam with the codes may be bad/defective...
Was able to log it. When misfires start, all cams appear to drop to 0.07 degrees. Not sure if thats what it defaults to if it looses signal or something.
*Update* did data-logs and the issue of course didnāt want to occur when i was logging, but looking at both exhaust cam positions, i can say that i can completely rule out timing being off. 30 minutes of driving and average exhaust timing was only .12 off bank 1 from 2.
