  • @jemtec1

    One other important point.
    You ALWAYS want to subtract the meter lead resistance from your reading.. So, touch the test leads together (in this case, at 200 ohms) you will probably get something around 0.3. If you have 14.8 Ohms for example after stabilizing, subtract the 0.3, giving you an actual reading of 14.5 Ohms. :) This is especially important with more sensitive devices, and can mean the difference between actual replacement, and not replacing when its actually bad. Good video!

    • @isaiahpinkerton3445

      Good point, but i think the manufacturers account for that user error and people who need to measure more sensitive devices know this, already.

      @@isaiahpinkerton3445 most of the more recent and higher quality meters do auto calibrate.
      Biggest thing is just do the 200 ohm setting and touch leads to verify it’s truly “0”.

    Chris you saved me a bunch of money! I used my multimeter to test the injectors on my Chrysler 200C 3.6L. Each tested at 15.0 ohms, except my one trouble cylinder. That one tested at 33.0. Replaced that injector, all my engine warning lights turned off and it's running smooth. Your video very straight forward and the graphics made it easy to understand the discussion. Thanks!!!

    You forgot to mention that injectors are either high impedance or low impedance. A low impedance injector will have a resistance of around 2.5 to 3 ohms, while a high impedance injector will fall somewhere around 12-18 ohms. Good simple video on how to check 😎

    Also watch out for slow climbing reading if reading takes long to reach stable it is also likely a bad injector another check to do just to figure out what's actually failing is measure from each terminal to injector bodies sometimes it can be the internal wires have shorted to body if no reading across any terminal than there is likely a break in the wire hope this helps.

    Dear Chris, I have a 2004 Grand Marquis, (I'm the original owner, about 230,000 miles on the car) and have had an ongoing problem with the engine light coming on after driving the car for a while. Symptoms are rough idle after the car comes to a stop; usually slows down to around 550 rpm, plus or minus after 20 to 30 seconds of coming to a stop, followed by occasional shuddering on acceleration. I've had the car to two mechanics. Before taking it to any mechanics, several months ago I replaced all the plugs and coils. Lately, one mechanic replaced all the plugs, which had less than 11,000 miles. He replaced the number 5 coil. A week later I bought a new air idle control valve and a new throttle position sensor and had him install them. He checked for vacuum leaks and twice he told me he found vacuum leaks. None of these new parts or service have solved the problem.
    I put a scanner on to see what code appears when the engine light comes on. It's 0355, which is the #5 cylinder. Another mechanic noticed the #5 coil was somewhat loose. He noticed the thread was stripped on the coil bolt, so he dropped a piece of plastic wire tie in the bolt hole of the manifold, and that made the bolt tight. Then he used a couple of plastic wire ties to secure the connector to the coil. He erased the code, and the engine light stayed off, until I drove the car about 20 miles the next day, it came back on. On the last two gas fill ups, I put a bottle of lucas fuel injection cleaner in the tank at each fill up. I also tried spraying contact cleaner on all the coil connectors, and several other electrical connectors.
    Is there any thing else you might recommend or (GOD FORBID) should I take it to a Ford dealership?
    Thanks for all the help you give to so many people !!!

      @tompastian3447 2 роки тому

      @@mmiller1188 HI Mike and I'm thrilled that you replied. YES, I got it fixed, and I can probably help you get your problem fixed. I live in Miami, and first I'll tell you I went to about 6 Ford dealers before finding a seventh who fixed the problem. I found a guy on youtube who was a Ford Master Technician, who explained the problem, something the first 6 Ford dealers did not even mention, and did not even suggest. IF you have replaced plugs and coils, and other parts , and you still have misfiring, then your main computer needs to be reprogrammed. First , you need to find a Ford Dealer who will reprogram your main computer. Symptoms of a main computer that needs reprogramming are 1. engine light continues to come back on 2. rough acceleration 3. Eventually the misfiring will shut down your AC compressor , a built in feature that protects the AC compressor. Once the main computer is reprogrammed, that problem will be corrected. It is remotely possible to reprogram your own computer, but probably more complicated that you or I would want to risk. You first would need a bidirectional scanner, which allows you to reprogram your main computer. You would have to purchase a "FORD" subscription when you purchase the bidirectional scanner. Then you would need to know how to to reprogram the computer using the scanner.
      If you take it to a dealer that will reprogram your main computer, they will check for any bad coil connectors, bad vacuum tubes, or any other problems related to your ignition. Before I knew the main computer could be reprogrammed, I wasted a lot of money on mechanics replacing parts that did nothing to fix the problem. I tried replacing all the plugs and coils, and still had the same problem. IF a dealer tells you that you may need to replace the main computer, I would be skeptical. FIrst ask them if they can reprogram your main computer. If they tell you that can't be done, find another Ford dealer. Pines Ford in Pembroke Pines FL, did mine. The last time I had it there about 2 months ago, they replaced all the coils, replaced two coil connectors, reprogrammed the main computer, total price was 940 dollars. On a previous visit, they replaced a coil and a vacuum tube. IF you know the mileage on your current plugs and coils,
      if there are a lot of miles on them, then have them replaced before they reprogram the main computer. Ask the dealer to inspect the coil connectors, vacuum tube, etc. if you have your plugs or coils replaced.
      Let me know if you have any questions, and how things work out.

      Corrrect. Dirty or clogged injectors would read perfectly fine. The "solenoid" chris describes is simply a copper winding that becomes magnetized (just as passing current through a wire wrapped around a nail makes it magnetic). An injector with an intact solenoid should read to have a very low resistance.

    I was showing a #3 misfire so I did a complete tune-up. The tune-up made a big improvement but it still shows a #3 misfire even after clearing the codes. A compression test said the engine is fine. The shops want a average of $100 just to diagnose. . One mechanic told me that all these fuel additives don't really "clean" an injector; if an injector is "bad", cleaning it won't help. Interesting. That would mean that all these fuel additive products are a rip-off!! Another shop said they will clean the injectors (without removing them from the engine) for $100. That could possibly be a rip-off too? From what you are saying, I should test the ohms and also the fuel pressure.That sure seems easy and simple enough.

      Holly Metcalf It's true, most of those products that you can buy in a bottle aren't really that effective at cleaning your fuel system. While they do contain chemicals such as ether that CAN remove deposits, the problem is they don't remain in contact with the surface of the fuel-delivery system long enough to achieve the desired results. The only way to do this is to remove the injectors and soak them in powerful chemicals and/or mechanically remove the deposits. Consumer Reports did an article on these products a while back, and their conclusion was that these products are a waste of money. CR doesn't take ads (they are supported by subscriptions), so their articles are objective.

    Hi Chris, my ohm reading are jumping all over the place. Also if they do stop at one number, when I come back to check them, the reading will be different. I read somewhere that this means the coil is partially open. Does that mean the injector is bad>

    I have watched this three four times to make sure I get this right. I have a pt cruiser 2.4l turbo the same multimeter set on the exact same settings. The numbers were all over the place high hundreds to nothing the reading numbers never stopped. checked them off the car on the rail, individually and back on the car. Whats up with that??

    Ok that is testing the injectors. What about the wiring and plugsthat come from the PCM/ECM and plug into the injector port?

    I have a 2007 Jeep Liberty, My Question is, Would A Bad Fuel Injector Shut Off The Coil Pack From Working? I started My Jeep up and Check Engine Light Came on, P0204 and a P0304. I did that test where you unplug the coil while the car is running and no change in cylinder #4, So Ichanged The Coil Pack From Number 2 and The #4 Coil Pack Worked on The # 2 spot, but the #2 Coil pack Did not work on the #4 spot. So I am Confused now.

    Hey Chris!
    Ran a fuel pressure test on my 2003 Ford ranger 4.0 and KOEO result gave me a leaking pressure. Started at 55 psi and leaked to 0 in a matter of 2 minutes maybe less. Cranked the engine up and it was at a steady 66 psi (manual says 64 +- 8). Should I check the injectors and if so, do I disconnect the battery terminal? Also, I don't see a fuel pressure regulator like on your vette so I don't know if I can check the vacuum line for gas smells. Thanks!

    Hey Cris my son has a 2002 Nissan Xterra I have replaced everything on the vehicle maintenance wise. He has been randomly getting a cylinder to misfire it’s very intermittent some days his car will run perfectly fine some days it won’t run right and it will send the engine code P0 302. If his injector was bad wouldn’t that be a constant and not intermittent like this
