95 2.5 litre with Auto trans:
Starts on first spin when cold (and it's been Ver-r-ry cold here lately!) -then comes down off fast idle to the specified 800 or so RPM -BUT after a minute or so idle jumps up to 1200/1300 RPM and stays there as long as I leave it running. Then when I shut it off it won't start again 'till it's stone cold again! I've tried the floor it to override the injector presets but doesn't fire there either.
-Fuel pressure is fine (checked)
-Sparks are fine (checked)
-Replaced UIM gasket/o-rings 3 months ago and WD-40 test negative.
-No Codes (EEC-IV on the 95's)
--------Any ideas on what to look at next?
