1996 Pathfinder 4WD. Car started shuddering. Engine light came on blinking first, then solid. Next morning engine light still on but running more smoothly. I hooked up code reader & it was kicking out P0305.
Cleared the code & it ran fine for a while, then did the same shuddering/engine light thing.
Is it just coincidence that I relocated the knock sensor the day before according to the you tube video? Or is this related?
I'm wondering - if this is an ignition coil replacement issue, how important is it to replace all coils instead of just the #5 coil?
