Hello all, I had a few quick questions for those more experienced with this 3.0L motor.
I just bought the truck with around 120k miles on it, and it had a little issue. If given enough time, I am talking like 10-15 minutes of idling, to the point where it was warm, it would to start to sputter, and then miss badly on cylinder 4, the CEL did come on and flash. If you just restarted the engine, you would be good for another 5 minutes or so. Since the truck was pretty old and the wires/coil looked OEM, I first replaced the coil, wires, and plugs to their OEM Motorcraft components. This helped drastically and I have not seen the code yet while idling, and the truck does idle smoother. However, now every so often the rpms will drop (normal 750, then drops down to around 500 or so), and it will feel like it is missing again just for a brief moment, but there is no CEL. So my questions are,
- Is this "rough idle" just a normal thing for the 3.0L?
- Any other things I should look at replacing on such a high mile truck?
- I hear a tick that increases with rpm until it fades, but then returns as soon as the gas is let off. With a stethoscope, it sounds like its coming from an injector, should I look into replacing those as well?
- Apparently, some exhaust valves didn't seat properly in a few 3.0L motors, causing cylinder 3 and 4 misfires due to a loss of compression, is a compression check in order then? or should I not worry about that with such a small miss
