hooked up my x431 Pros mini to see what the codes were, and it showed misfire on cylinder #4.
After replacing the lifter I could still hear a little knocking, ticking coming for the same side of the engine, it was nothing compared to before that had an awful sound like it was grinding metal.
thinking I might have messed up somewhere I did a compression test on cylinder #4 and it shows 150 PSI.
i hook up the scanner to see live data and this is what it shows, not making lots of sense to me. Funny thing is that on the live data while idle shows misfire starts at 1 all the way to 199 and resets.
if I press the accelerator pedal to 2,000 RPMs the misfire doesn't happen any more on cylinder 4 and the engine feels smooth.
i even swapped the spark plugs and ignition coil from the cylinder right next to that one to rule out any possibility that it was the ignition coil.
also check injectors they are all reading 14 ohms.
here are some pictures maybe someone out there knows what he is looking at.
have the same problem?
