that has to be the most ive seen anyone stretch a fuel problem... it similar to a bad temp sensor, i'm having similar issues and at times worse and i cant keep getting bad fuel over n over n over again... besides there are other teltale signs that its my temp sensor....

i thought stock gap was .026.... .028 sounds large

What is a temp sensor, and where is it on the car?

Temp sensor is CTS - coolant temperature sensor, it is located below the thermostat which is at the engine-end of the top cooling/radiator hose (this is true for 98 x70, it is likely the same location for your 850).

When my CTS was failing, the symptom was engine running hot and poor mpg.

If you should replace it, together with the thermostat, be sure not to round the torx bolts by using quality tools. Some here suggested replacing those bolts with new T-Stat housing bolts - part number is 986228.
