- 2003 Ford explorer
My 2003 explorer began a rapid pinging/knocking sound and started cutting out while highway driving as if when the fuel filter is clogged changed spark plugs recently and was running beautifully. Diagnostics machine says *too rich mixture *misfire on first 1000 revolution *and 2 more for misfire but didn't specify anything more..recently purchased just passed dealer warranty have researched and have no idea signs point to sugar had no cutting out issues service lights etc going on have been replacing tune up parts
