88XJSteve

So I got everything started and it runs fine (been working on it for 3 weeks)

And now when I accelerate or slowing down and a couple times it just died from me driving straight. Well basically it sputters and then dies or if I turn into a driveway to turn around it just dies. But the weird thing is that sometimes it will not die so I'm kinda confused.

Specs are:
88 XJ
4.0L
AW4
242
Auto

Let me list all of the things I've replaced SO FAR lol

Cps
Knock sensor
Map sensor
Tranny
X-case
Dampner pulley
PS pump
Water pump
Valve cover gasket
Oil pan gasket
Plugs & wires
Distributor cap and rotor
Idler and ac pulley
Serpentine belt
Alternator
Ignition coil

Now I replaced the alternator today and the voltage is better but it still shows around 12A. Could it be as simple as the battery? I mean the battery has been sitting for over 8 months in the jeep before I bought it.

Thanks for any help
Steve
