I looked at a few you tubes on this.
Oh well thought I'd ask , anything at this point to avoid taking things
apart then find it's just one hose or something simple.
All I know it it runs fine for close to 2 minutes only when it's cold and
sat over night then it begins this erratic miss . How hot can it possibly
get in 2 minutes? The RPM does not drop in that time frame . With the
airtemp sensor in when cold I unplug it gets a bit worse like it needs it
then , after the 2 minutes unplugged clears it up..
I'm going to replace the lines to the trans and AAR to intake and check
the PCV first then go from there.
