94 Octane

SP 34C delta

Used about 1 gallon of ethanol and a bit of octane booster for this

Tried to log a WOT V5 pull for you and got codes. The second log is me driving the car lightly after I turned the car off and reset the codes. It is shuddering on acceleration which you will probably see.

It happens here in both these logs. Hope you can tell me what is wrong, it is happening quite a bit and I can almost reproduce the problem every time. It happens in any gear as long as I get back on the gas at pretty low rpm. For example, if I am approaching a stop sign in 2nd and I hold 2nd to like 1500rpms so I don't have to downshift to 1st, and then get back on the gas with anything over 1% throttle, it happens. If you need a clearer/shorter/more isolated log of it happening I can get you what you need. If I need to log any other parameters, just let me know I got you.
