8v92TA DDEC II surges like this when I let off the throttle driving slowly through the city. Is this a setting somewhere in the DDEC computer that we can adjust? See video below:

When it does this are your Jakes on?

Hi;
Also check your air cleaners. How long has this been going on?
Merle
cold oil ???
Geoff: no jakes :(
Merle: coach has been doing this since Ken and I adjusted the ECM fuel tables.
Don: it does it when completely warmed up. Driving down the road and lifting the throttle while coasting to a stop it does this.

Is it throwing any codes?

then my guess is you needs to tighten some part of this parameter...tho it sounds to me like it is not an "all cylinders/all injectors problem".. if it is rythmic..then it is the same miss/stumble as in the same cylinder/s...
John, that's the rub. I won't know until I get it on a prolink. Idiot lights are wonky. I've been fixing dash electrical stuff little by little.

Scott I bet Ken will be getting in touch with you soon.
uncle ned
I can't view the video (problem w/my laptop) but I'm sure it probably has something to do with the settings you guys did on the DDEC.
I'm also with Ned, if Ken knows there is a problem he will go to great lengths to learn about it so he can correct it.
I have always been impressed with Ken's work and totally confused by his computer knowledge.
;D BK ;D
It could be the turbo sensor trying to figure out what is going on with new setting, Arnold will figure it out the DDEC 11 is a strange animal
