An engine misfire may develop due to a failed ignition coil. Our technicians tell us one coil is used for each cylinder. If one fails, often times another is not far behind. It may be worth considering replacing all the coils if a failure is encountered.Google+

THE VEHICAL WOULD DRIVE FINE AT TIMES AND THEN IT WOULD INTERMITTENTLY MISSFIRE OR SKIP. I COULD FEEL THE VEHICAL HESITATE JUST FOR ONE SECOND AND THEN IT WOULD DRIVE FINE AGAIN. THE PROBLEM WAS MORE NOTICABLE WHEN THE A.C. UNIT WAS TURNED ON.

Started with misfires while running the a/c and then started to really lose power when going up a hill or turning a corner and would feel much more of the misfiring. Check engine light came on eventually.
I replaced two o2 sensors and then the spark plugs, wires and boots and now I am working on the coil packs my problem with my van is it won't stay running and when it does it puts like its not getting gas but as soon as I hit the gas pedal it moves fast...

Vehicle would miss under load (air conditioning) and hot conditions - particularly noticable at stop lights. Idle was very rough at these times. Occasionally a rare miss at highway speeds.
