This graph is on the highest smoothing setting. The "internet" says fueling issue which makes sense. I had a aux pump installed but later on found out it was never plugged into the fuel harness. Kept getting a code but the shop just turned that off so it wouldn't throw a code. So I'm leaning towards the computer pulling timing due to fuel operating parameters set by the computer. Does this make sense on why the graph is so jagged or could it be something else? Thanks
