Hi All,
Been fighting with the Exploder (4.0L) for about a week now. Problems started when my wife said the car started flashing the SES light and was running like garbage. She limped it into Autozone and they pulled codes:
P0401
P0300
P0306
P0301
Anyways. I know the EGR valve needs to be replaced. I had pulled it off and thoroughly cleaned with carb cleaner. Re-installed it, but it still runs rough. SES light came back on and the only code it threw was p0401. I believe the valve may have been stuck open, causing the misfires.
Seems to be low on power. Roughness isn't unbearable, but noticeable (moreso at lower speeds). Gas mileage at lower speeds is AWFUL. Seems to be normal at highway speeds.
At any rate, I was poking around under the engine bay, as I'll be changing the belt tensioner this afternoon. I was playing with some of the vacuum lines to see if I could track down a leak somewhere. While doing so, I was getting a systematic "click" from the engine bay.
For the life of me, I cannot track down the source of the noise. It appears to be coming from under the intake manifold, but can't be sure. Sounds like a switch of some sort. Was hoping someone here might have experience and can pinpoint it for me. Please take look at the video and tell me your thoughts.
* It is not coming from the AC compressor clutch engaging *
Thanks!
