M156 Misfires on one bank [Weistec SC]
I'm getting Misfire Codes in "Pending" mode, not as actual/active trouble codes (no check engine light).
P0306 - Cylinder 6 Misfire Detected
P0308 - Cylinder 8 Misfire Detected
P0305 - Cylinder 5 Misfire Detected
However today, when car was started in the morning, check engine light came on and engine was running jerky at idle. immediately turned off ignition and started car again, and it started normal and smooth...
Connected OBD diagnostics and got same trouble codes + 7th Cylinder, which never appeared before. (P0307 - Cylinder 7 Misfire Detected)
So I have all driver side Cylinders as "Pending" trouble codes....
Spark Plugs are Birsk with 0.711mm gap.
Car is running fine and smooth, both on idle and WOT.
Strange thing is that it is only on one side.... I have switched location of spark plugs as well as coils, however I'm still getting this misfire pending codes on 5 6 7 8th cylinders.
What would you advice to check?
Thanks
