Resolved Random stalling (log)

[eclipto98]

So when ever i push in the clutch i seem to stall, pretty much everytime i push in the clutch above 900 rpm it stalls. im not sure what the next step is but i do know i need a new o2 sensor. i adjusted my tps and raised my idle via link but still nothing.

will bad o2 sensors cause this

I'm on my phone now so I can't check the log but please explain me something it stalls even at idle?
And what about some load like turn AC on it stalls? If so you might what to check the ISC it might be put of range or bad! Later I'm gonna be able to check the log so I can help you better.

no it idles, but if i step on the gas and let it drop it just dies. i dont have ac so idk. i do have a lightweight flywheel. if i put it in neutral from anything over 900 rpm it just stalls sometimes it catches itself but 9/10 it stalls

I had a similar issue when I removed the coolant lines going to the throttle body. Are the lines to the throttle body still connected?

 

[eclipto98]

yes they are

Like eclipsyco said, test the idle motor with a multimeter. Also, check for vacuum leaks, mechanical Timing, and ensure you aren't venting you BOV to atmosphere if you are still on the stock MAF.

Log ISCPosition. Your BISS screw most likely needs adjustment.

Did you ever change your deadtime????

Your AirflowPerRev value is rising as RPM's drop causing the car to stall, just go to your IdleAir tab in Link and enable it. If the base table doesn't fix it follow this

Gofer got it right! Sorry I didn't have time till now to see the log.
You are missing many values on that log (not captured) also the front o2 sensor is not cycling at all...
Now you can follow Gofer's suggestion but if I may I would suggest first before attempting to tune anything and if the car is stock please fix the o2 sensor problem first and get your idle values in check like ISC, BISS screw, TPS, Idleswitch, no boost/vacuum leaks, etc.
By doing the above you might actually end fixing your problem...
I know it might sound like a lot to do but those values and a correct working order of those sensors are needed for further tune!

His deadtime supposed to be set at 0 since he's on stock injectors too. That's why he's running rich causing his 02 not to cycle

i will give that a shot. i changed my dead time and mad another log on the freeway, i do plan on changing the o2[DOUBLEPOST=1410279379][/DOUBLEPOST]
