My car stalls. Not when I'm stationary but when I'm roling to a stop in neutral.

I'm not sure if this is a recent occurrence or if it's been going since my last tinning session. Or maybe it's the cold weather. I've only really noticed it at night.

I know there are settings for the Idle Control Valve that are speed dependent and will look into these. Any other ideas?

 

try raise the idle a touch?

 

I don't think so. The idle sit's at around 900 when stationary which is good. But when cruising to a stop it drops much lower and stalls. I'm guessing my problem is more to do with the speed at which the ICV takes over than the rate at which it idles.

 

Post your settings under Options -Idle

 

Do you have a wide band? if so watch it when it dose this, if its going lean then its a fuel problem. Im currently trying to hunt down the same problem. Mine goes lean in neutral sometime when I pull to a stop for no reason at all.

 

Hi idle car speed 23kph
Hi idle rpm offset 200rpm
Hi idle wait time 0.38s
Idle off if TP over 0.39%
idle FB above rpm 400rpm
Idle FBbelow rpm 2000rpm
Idle A/C Load comp -14.06
A/C On delay 0.90s

 

I had the exact same issue only under neutral whilst rolling to a stop at a set of lights etc.

Touch up tune sorted it out.

 

A stcok s2k has this issue (not stalling but it'll shake and "want" to stall) so it is normal to a point. Prob need a little touch up on your tune. Maybe clean your IAC as well.

 

I'm not familiar with the aem stand alone, but sounds like you need to find the "ISCV Controls" and add 5% at a time until its fixed in the hotter region. There should be 3; idle, driving non-ac and driving a/c. Adjust the driving two and things should be better.

Cheers!

 

to me, i think your iacv settings are off in the lower part of the rev range. if you go to the idle settings and raise it a few notches in the 400-800 range it should keep teh car running. the iacv valve regulates the air when there is no throttle.

my opinion is the valve is closed too much when the idle drops down in the 400-800 range.

you could also make sure timing in the -10psi to -13psi range in the 500-1000 rpm range is about 5 degrees.

then there is also the timing offset tables for idling and fuel offset tables for idling.

lol come to think of it, no wonder people say aem ems is a pita to get to idle. theres a shit ton of things to tweak.

bottom line, tuner can fix this. its something in the tune.
