Hi! I have a '96 Explorer with the 4.0 V6. I've had my spark plugs changed twice within the last year because the Number 4 sparkplug has lost its electrodes.
After I start the car each morning the car runs rough for 2 minutes, then smooths out. Today the "Check Engine" light came on... computer code P0304 - misfire on number 4 cylinder - ARGH!
Questions are:
1) What could be causing this? 2) Which cylinder is Number 4? I think it's the driver's side front - is this correct?Thanks, ...Jerry
