Hey I just bought an Actron u381 code scanner from e-bay, cost a whole $65 and change. Does anyone have experience using this scanner? It's supposed to have live data reading..will that allow me to find which coil-on-plug is giving me issues without the check engine light being activated? I called my mechanic and he wants almost $200 to replace a coil-on-plug, when I can buy one for $50 at Advance Auto Parts..$65 isn't much to pay to save hundreds of dollars at the garage, these damn Fords go through cop's like a fat kid goes through candy.
