We have a 1996 Geo Tracker 2WD 5 speed manual 1.6 L 16 valve vehicle.
It is setting the PO400 EGR code -
The symptons are:
After warming up the vehicle will stall after driving and stopping unless I let the engine RPM come up from almost a stall speed to normal idle operating speed (800 RPM). Once I have done this once the vehicle will drive normally and idle properly without stalling until I shut it down. I have also found that if I hold the clutch in and cost to my first stop without letting it coast to a stop with the clutch engaged, that it will usually stall before it has a chance to come up to idle speed - if I do an immediate restart and let it come up to 800 RPM idle all is well afterwards until shutting down - then you go through the whole drill again.
I have pulled the EGR valve and it is clean and doesn't seem to stick when operating with a Mighty Vac pump. Am not sure if I have gotten the line completely cleaned that comes from the Throttle body. Have access to a scan tool and have OEM manuals.
