    You also could use a borescope by removing the spark plug they are out already you could look at the top of the cylinders😮 to see if it has a hole

      Mine has oil I think or fuel idk but it’s in my cylinder head, but I had a misfire on cylinder 3 and checked my cylinder bores and they all look dry except that cylinder 3, did a compression test and got around 165-175psi but on that cylinder 3 I got 30psi😩do I need to get a new engine???

    My car has never overheated but I have a misfire on cylinder 3, spark plugs, ignition coil, and fuel injector have been checked and all is good. Would you recommend I do a compression test? Or should I first check MAF, fuel filter or is there anything else I can do or check? Thanks for the video and sharing your knowledge.

      definitely check if for anything else check the overall health.. unlikely to be your situation but i had a misfire on my car from a valve cover. I'm guessing your spark plugs were dry when they were removed.

    I did a compression test on my 2002 Ford Explorer 4.0l v6 4x4
    It looks like cylinder 3 might be an issue, and 1,2 & 3 is not consistent with 4,5 & 6 cylinders.
    Here's the readings I got.
    Dry test. PSI
    C1. 130
    C2. 135
    C3. 119
    C4. 143
    C5. 144
    C6. 148
    Wet/oil test. psi.
    C1. 135
    C2. 137
    C3. 125
    C4. 148
    C5. 151
    C6. 155
    Have you come across something similar, and what do you recommend I would do next?

    One of my spark plug has no compression. Mechanic is saying too much money to inspect further and for me to buy a second hand engine. This sound right?

    Do you know about ford trucks? I got a 91 Ford f350 7.5 and i replaced almost everything new and still misfires. MAP sensor. Purge valve. TPS. EGR valve position sensor. Fuel injectors. Spark plugs and wires. Distributor cap and rotor. Ignition coil. ICM. Air filter. I even did a engine flush. I even check the PCM. Coolant temperature sensor. Air intake sensor. Like its not hold idle. One minute its ok then next minute, it misfires. Then back to running fine. Then back to misfire.

      Timing is off or firing order is off. I assume it idles rough and runs okay when in speed.

    On my 3.3 did the test my highest was only 90 all the others were 60 ...only 80k miles im guessin im goin to have to swap engines ?? Extremely rough n u have to mess with it to stay running ..if u try to give it gas it acts like its starved of o2 ..but no vac lines are bad , plugs n coilpacks changed ..fuel filter checked , ran absolutely fine all day never overheats. Never stalls no power losses...filled up with gas 20 minutes after the truck filled their pumps(didnt know they just had found out out from clerk next day ) ..went to start it and its sounded abysmal after starting...never in 53 years saw an engine be 100% fine and come out 12 hrs later be f@cked like this
