Random misfire

[None2Slow]

I have random misfire codes, all showing drive side. P0306, p0307,p0308 p0300 and p0316. Clear them, then will get p0308 and p0316. Would a broken driver side motor mount cause a misfire code? I've changed the plugs and coils and codes still randomly come up. Also have done a crank relearn just in case.

I’d think a broken engine mount would be more likely to cause knock rather than a misfire.

Pull the plugs and check them. 6, 7 & 8 are the back 3 cylinders on the drivers side.

Have new plugs and swapped coils around. The codes randomly call those 3 cylinders. 1 day it will be #7, next it might be #8 and sometimes all 3. Changed the plugs 2x already and no change.

My next step would be to do a compression test on 5 -8 and see if there’s a difference.

check the vvt solenoids.

check the vvt solenoids.

How do you go about checking the VVT solenoids?
