87 cherokee stalls out
 

my Dads jeep stalls out when you go from park to drive. you have to put it in neutral start it up us the brake with one foot and idle up the engine the shift in to drive once your going seems to be ok. don't know what to check.

Here's a great place to start:

Anyone with an 87 to 90 Renix Jeep has two or three minutes to see that their
CPS is putting out at least .35 AC volts. I don't mean to come off rude, but if you can't connect a meter and turn the key, we may not be much help.
AC voltage CPS test; Small clips on the meter leads really helps. (you need contact with those little pins while it cranks)

Unplug the connector at the back of the manifold with wires going down to the bell-housing/cps. (it's a three wire plug, with only two wires)
Probe the two wires to the cps with the digital meter set on AC volts, a 200 scale on mine. Yours meter may have a lower, or “auto range”.
Crank the engine and note the voltage. (jump it if your battery is low). .35 (about 1/3 of a volt) is minimum. >4 to .8 is more like it.

Now, I highly recommend you click on my signature and take a look at Cruiser's tips right on top. These Jeeps are known to have issues with the grounds that can have you chasing your own tail all day and getting nowhere! Good luck!
