Hey guys,
My spark knock is back with a vengeance.
It is now at the point where even on a tank of high octane, it still knocks, which it did not do before.
I had my scanner plugged in watching some live data and the timing advance was pretty normal, but I did notice the fuel trim varried from +3 to +8, hanging about half the time at 3 and half the time at 8.
What does this mean to you? My understanding is that this means the computer is trying to add fuel. Does that mean I could be running lean, hence knock is back?
I have no CEL, havent had one for weeks since fixing my P1443 code.
Thanks
