Hello all,
I've been trying to rectify poor idling and reduced power on my 1999 Ford Ranger xlt (3.0 flex fuel) for months now. As of now, the truck won't throw a code but long term fuel trim banks are hovering around -7.5, and it remains in a closed loop no matter how long I drive it. Additionally, the dashboard coolant temp indicator is not working.
This is where I'm wondering if the thermostat is bad and I need to replace it, or if I should replace both of the sensors attached to it, maybe the whole damn assembly?
Also, I'm having one hell of a time finding part numbers for any of these items. How do I look these up? They aren't listed in the Haynes manual anywhere and internet part finders are often wrong (especially Amazon's).
Thanks in advance for any advice you can give.
