I have a '92 4x4. I recently had the thermostat replace with a Ford 195 degree thermostat. However, the temp guage runs about midway now where as before it would never go past the "N" in normal on the guage. Also, since the thermostat replacement, the engine has developed a pinging when going uphill. Running a higher octane gas helps, but why should I have to except this change. Is it oxygen sensor, timing, plugs or what? Thanks for any help
