Okay, so here's the situation. Intermittently, my car (00 civic si with jrsc) will bog down real low almost to the point of stalling (sometimes it does stall) and it will last for 30 seconds to a minute or so before it rights itself. It only does this during cold temperatures, typically when it's below 32 degrees out. Once the car warms up it's fine and it's also fine when it's not cold out.
I'll attach the datalog I took and also my calibration. Right now I'm just using a basemap calibration with a couple minor tweaks because I thought maybe it was something with the tune my tuner did for me (which was about 2 years ago).
Well, I was trying to upload the datalog, but it's not letting me for some reason. Is there a size limit for the files? Anyway, in the datalog that as of now you won't be able to see, between 30 secs and 2:45 the MAP value rises way up to around 10.4 psi which decreases the degrees of ignition to around 2 and pulse width of the injectors rises dramatically to around 11. This is all with the car in neutral in the driveway and me giving it enough throttle to keep the rpms up around 2k.
I'm thinking it might be my MAP sensor, any ideas?
Edited - datalog uploaded
possible map sensor failure?
