Random fuel cut

[raiden808]

I had an issue last week where the throttle would spike and jerk randomly. Did a data log and it was the saw Throttle position sensor wasn’t reading correctly. I replaced it and it was working fine for a week. The issue now seems like there’s a fuel cut at around 3500 rpm. Re-uploaded the stock calibration and it’s still acting the same. 2003 Civic Si K20a3 I/H/E kpro v3 with stock calibration.

Here is the data log. My morning drive didn't have any issues but my afternoon one did.

Have you tried disabling the lean protection?

[raiden808]

I'll give that a try.

That seems to have worked but didn’t get to open it up that much due to traffic.
