remove the intake tube to the throttle body and lean off the carbon on the
throttle plate and bore see if that helps carb cleaner works ok but the
parst stores sell the throttle cleaner that is more money

Re: '97 Jeep Grand Cherokee Laredo 4.0L stall problem
 
I got some throttle body cleaner and electrical cleaner and sprayed
everything, then put some dielectric grease on the sockets. There
were some carbon deposits around the butterfly. I also replaced the
air filter just to make sure that was good.

Seemed fine once I started it up, though it was a little hard to get
started. I'm not certain if it's fixed, since the problem only
happened very occasionally, but it's good now anyway.

Thanks for the suggestions, guys.

might be the torque converter- that happend to me. it would stall at
lights sometimes, and it would cut out if i went from drive to reverse
or back, but not if I paused and held it at neutral for a couple
seconds. we had a dealership fix it, so i dont know if they screwed
us or not. it cost us around $1000.
