high idle stalls when accelerating Plano TX
Hi, need some help diagnosing a problem.
2000 7.3l automatic just turned 200k on the OD all stock
Occasionally of course when I shift from drive to Park or Neutral It will Idle up to about 1k for 5-7 seconds before dropping back down to normal.
Second symptom is that when first starting out truck will stumble/die when accelerating from a stop. After it warms up it seems to be fine. When it does this it starts right back up without issue
Can not disengage overdrive (checked the wires and they are fine still) - fuses are fine
After the truck stumbles and I shift back into park OD light flashes, but I am not picking up any codes, but have only a basic scanner
Just changed out my transmission range sensor and flushed the tranny with new ATF- old fluid looked good with no parts in the pan
Everything else seems normal once it is up to temp
IPS and CPS were replaced 6 months ago
Connectors on IPS, CPS, IPR and Transmission range sensor all look good
Need help anyone with AE in the Plano/Frisco TX area?
I think it is a sensor related issue as it started out of the blue and is intermittent. At least I hope so and it is not my tranny going
Going to check the UVC harness next but need ideas.
need help as this is now my daily driver
