| | Odd misfire issue on 2014 SS 1LE
Ls3, replaced valve stem seals recently, put fresh plugs, wires.
I have a slight miss at idle-2000RPM and it sounds like its running on 7 cylinders.
so i enabled my misfire detection back on in HPtuners (I have a SRD LS3 Cam, 233/248)
Cylinder #3 had the miss, So this is where it gets weird.
the plug was fouled, put a fresh one in, no go, the header primary for #3 was dead cold.
checked the arc on the coil to the plug wire and it's weak as hell.
I swapped coil #3 to cylinder #1 and the Arc was a LOT stronger, and the coil pack that originally came off of #1 was arcing weak and the primary was still cold.
I then swapped the entire driver side coil pack rail to the passenger side and #3 is still dead. Even tried a coil pack harness i had laying around. (put it on backwards at first LOL, sounded like gunshots)
anyways. I'm starting to think the PCM is **** or the car developed an engine harness problem out of the blue. The grounds are tight and making proper contact. I can't think of anything else guys. This car is my Daily and i pretty much need it to get to work and back.
If anyone has come across this issue let me know or if you can provide me with a pinout of the e38 controller I would sincerely appreciate it thanks
