    Cylinder 4 misfire and events

    I've already replaced the plugs, wires, tested injectors, moved injectors, ran a noid light test, a spark test, a compression test and tested the coils. The problem is that there is NO, read 0 PSI, compression on cylinder 4. I pulled the valve cover today and all of the followers are still...

    Cylinder 4 misfire and events

    I was able to run a compression test today. I get between 154 and 167 on all cylinders except number 4. That cylinder has 0 psi compression. Tuesday I will be pulling the valve cover to look at it and pull the head if needed.

    Cylinder 4 misfire and events

    hades02 I have no leak there anymore. That was cleared up the night that this first began. I have changed all the plugs now and the plug wires. The problem still exists. I have removed the plug wires one by one and the only one that does not affect the engine is cylinder 4. The odbII graph still...

    Cylinder 4 misfire and events

    I have looked at those sites you linked to. That is why I did the spark test and the coil pack check. Per one of the sites, it suggested a compression test. Due to my doubts of the caliber of work done by the previous owner and the noise that the engine made during and after the misfire...

    Cylinder 4 misfire and events

    I didn't see any links. I have already looked at several different sites. I'm not new to engine work, this is however the first Ford I have ever owned.

    Cylinder 4 misfire and events

    Well, considering I will have the plugs out already, a compression test will take no time. Determining if it's the valves or rings can all be done while running the compression test. In other words I will spend no money on the test and only about 30 minutes more than changing the plugs. Since...

    Cylinder 4 misfire and events

    I read my original post, when I said "cleaned the plug wire". I should have said removed all the water from the leak. When I said "needlessly spend", I just want to rule out any big issues before I started replacing the electronics. If the compression test comes out bad, then I'll determine...

    Cylinder 4 misfire and events

    I did not clean the wires. I did not do anything with the wires other than using a spark tester to validate power was reaching the plug. I have replaced plug 4 with an Autolite double platinum plug. I will replace the other 7 plugs tomorrow and while they are out run a compression test. I plan...

    Cylinder 4 misfire and events

    This was a visual check from a spark tester. Not sure when the last time the plugs were changed. I just got the vehicle. I replaced plug 4 and have plugs for the other 7. My major concern was that I had a ring or valve issue and I didn't want to throw money into wires, coils etc if that was the...

    Cylinder 4 misfire and events

    Test I removed the fuel pump relay and tested the wires using a spark tester. The spark was the same on cylinder 4 wire as on the other cylinder wires. As far as I can tell all tests a pass. However I do not feel the wire clamp onto the plug on cylinder 4 the same way I do on cylinder 1. Yet...

    Cylinder 4 misfire and events

    Tomorrow I will be running a spark test on the plug wires and the coil packs. As I stated I changed the specific plug that caused the code with no noticeable benefit. If the plug wires and coil packs pass the spark test then I'll move on to checking the injectors and lastly a compression test to...

    Cylinder 4 misfire and events

    I have a 98 4.6 W series Expedition with 200k miles. Driving to go visit family on the interstate (70 MPH), the truck began to lose power. Cruise control was on so it floored it to 4500 RPM. I pulled over and the engine died. Checked oil. It was fine. Saw a small leak from the heater hose to...

    Engine Temp / Heat

    Yeah I had heard this on several forums. Tomorrow I will be flushing the heater cores again and replacing the water pump. I'll report back what the results are.

    Engine Temp / Heat

    No gurgling noises. Also my driveway is on a 40 degree incline and that's where I let it idle for 25 minutes. Wednesday I will tap into the lines and back flush all the heater core lines and replace the water pump. I've work on numerous other models of cars but this one has me stumped. I'd still...
