Scan codes p0300, p0301, p0302, p0303, p0304, p0305, p0306 and p0356.

Change all the spark plug with compatible champion pre gaped spark plugs, after that checked engine light turned off. After a long drive light came back. If gas tank is full light goes out but after few hundred miles light come back. Code means misfire. What next to check?

Hello,

Direct Trouble Code(DTC) P0356 is a problem with #6 primary coil with igniter. DTC P0300 is a generic cylinder misfire code, and DTC P0301-0306 are misfire codes with the last number being the cylinder that's misfiring. Okay, your engine needs basically three things to fire. Fuel, spark, and compression. Since you have a spark related DTC, P0356, let's start there. Here is a link to a guide on how to check for spark.

Thanks for information. I watch the video and try to test the cable and ignition coil, my cable has 4 pins and I was not sure which one need to be tested. I tried any way with out under standing the pin test with multi-meter. I did the spark test and spark was their. I swap my ignition coil from #6 to #4 position and scan, this time the result was DTC P0354, this tells me that ignition coil is not performing its function. Is this coil can be fix?

Thanks,

M.A. Shaikh
