I had broken EVAP valve to manifold hose. I replaced the EVAP and the hose. It is better, but, the problem still occurs.
I made some logging and I noticed, that it happens every time the MAP reaches it's maximum value, which is ~110kPa, which is weird, sinse barometric pressure is 99kPa.
I put MAP from other car, and problem is still occurring, so it is not the MAP sensor problem.
Any idea where to look for?
Log and tune attached.
