1988 Jeep Wagoner limited, 4.0 179,000 miles; I replaced the ignition coil, but it still stalls when we back-up or pull out. It doesn't do it all the time, it seems to do it when you ease on the gas

Some things to do.
Check for vacuum leaks. Leaky hoses and connections can cause an erratic idle and stalling.

Change your fuel filter. Run some fuel injector cleaner thru a tank or two. I like chevron with techron.

Clean the throttle body. Make sure it is tight.

Clean the EGR valve. Make sure it is functioning properly.

Change the PCV valve. I prefer OEM parts for this. Make sure there are no leaks.

I assume since you changed the coil the rest of the ignition system is also new. Properly gapped plugs, wires, cap and rotor(if used) can all contribute to stalling.

Good luck and let us know. :)
