Stalling under decel/ rough run and idle
First time posting, first time owning a cherokee. Came from a 1997 tj. I now have a 1988 2dr, 4.0, 5sp manual cherokee chief. It's stalling after upreving and rapid let off/decel and running very rough at idle. I've nearly replaced everything, including the whole distributor unit and I'm pretty sure the timing is right. But, after hooking up a meter to break booster, and checking vacuum, it's all bad. So, I guess I have to two options. Is it a retarded timing problem? Or should I go through the entire vacuum lines and manifold. Anyone have advice where to start? I don't want to mess with the timing if it's a vacuum problem, and I don't want to try and find a leak if it's a distributor/timing issue. Any help would be great, thanks.
