I just got my 2000 XJ (4.0L) back from the shop and lo and behold there is another issue with it. It was in the shop for a coolant flush, inspection, engine knock diagnosis, squealing aftermarket brake pad ... you know, the usual.
It was finished last week and I picked it up on Saturday. The engine knock (which I was told was piston slap by two other shops; they said it was a lifter sticking) was noticeable quieter -- turns out they said the engine was low on oil [even though I just changed it less than a month before / check it every other week] so they changed the oil and put Engine Restore in as well. While I know many people have had good results with it on JF, I'm still calling it snake oil and was pretty pissed it was added without my knowledge.
I drive the jeep over 2 hours on the highway back for work. Runs fine on Monday. Yesterday evening is when I noticed it was struggling to turn over (low whee whee sound for a couple seconds); but when it did, it ran just fine. No low battery reading. The gauge read just past the line before the 14V mark. This morning, I get the machine gun effect.
I hooked up battery cables to a friend's V6 mustang and waited about 2 minutes. It turned over without hesitation. I let it run for 5-10 minutes and grabbed my multimeter. It read 13.90V. Take off the cables and wait another 5-10 minutes and read the battery again: 13.83V. It sounded fine [aside from the quieter engine knock] so I cut it off and waited a minute. Tried restarting the XJ and barely got it to turn over -- same whewue wheuw sound as last night. It sounded very bad. Super low idling (2-300 RPM) and rough lug lug lug lug sound. Battery gauge was reading the same as before. Gave it some gas, sounded a little better. Let off the gas and it almost stalled. I gave it some more gas (~1500 RPM) then let off the gas and it stalled on me.
Any ideas? My first thought this morning was a dead battery. Then I thought it was an alternator issue, but who knows with this thing. Honestly, it's been so ridiculous with repairs in the past x number of years that I'm one major repair away from pushing this thing off a cliff.
Thanks in advance.
