    I've been having a super hard time figuring out the same code on my car this was a ton of help thank you

    My 4.8 all were around 155, except #6 had 125 ..So, nonetheless, it runs great, idles perfect. With 319.000 miles that pretty damn good. The thing to do is keep oil change and add some stp, or engine restore. I have no doubt I can get another 150000 miles of that engine amigo.

    thank you for your video, I have a 05 Jeep Grand Cherokee 3.7l with a 306 code has 75k miles. I replaced the coil 2 times and the plug. I really don't think it is likely that the rings are bad at only 75,000 miles and the jeep was well taken care of. how many hours should it take to replace the fuel injector on number 6 for this car that has external fuel rails?

    I had a truck that had a low compression too, but it wasn't that the rings were worn, or the piston bad, it was a bent push rod which affected the compression rate.

    so what caused the low compression ? was it a intake gasket leak or a piston issue ?

    Does the fuel injector has to do any think (problem) with PO306 code ?

    • @EliTheOBDTech
      @EliTheOBDTech  9 років тому

      +jerr dez In this case for this vehicle the injector had already been replaced. Misfires usually occur due to ignition problems such as: Faulty coil packs, sparks plugs, ignition wires, cap and rotor. Fuel delivery problems such as: Restricted injectors, leaking injectors and injectors not spraying fuel. Mechanical problems such as: Valve train problems, worn piston rings that cause low compression and jumped timing chain/belt. Sometimes even a bad intake manifold gasket will cause misfires due to a vacuum leak on the intake runners.

    So the problem is the gasket that covers the spark plug? Im not a mechanic. Was the problem fixed.

      +angbuzz Yes, it was the gasket along with spark plug tube seals.

      You may have a problem with the valve rocker arm/or valve lash adjuster for #6

      Yes, especially if the gasket is not sealing properly in that specific cylinder intake runner.
