You said OEM plugs which ones did they give you?
Note here on the CEG bang fo the buck the Motorcraft double platium. "AGSF 32PPM or the Autolite equivilent. sorry brain lock. I know the Motorcraft cause I keep the one of the empty boxes on a shelf above the computer.
Anyhow I know for sure the plug works. My Ole laptop with
www.obd-2.com software and have found misfires on new OEM plugs after a few thousand miles and not the misfires that would be bad enough to cause the CEL light to flash.
What this is is a test that is part of the OBD II mandate that monitors all the time and logs into the history. You can actually have misfires and not even tell it driving.
Anyhow after replacing OEMs, Bosch Platiums 15000 ago everytime I run the test not one misfire. The mileage on a trip went from 29.8 to 30.5 - 31.8 mpg. Which reminds me time to get the laptop out again the around town mileage is dropping time to run some tests.
