1988 Jeep Comanche Stalls, But Not In Neutral

[jnickle]

Hello.  I recently acquired a 1988 Jeep Comanche 4X4 4.0 Automatic.  My truck stalls but not in Neutral.  The truck will want to cut-off when I drive, but will not if I am pressing the gas pedal.  It will just cut out if I am coasting down the road.  The truck never seems to even threaten to stall when it is in neutral.  In fact, sometimes when I can feel a stall coming on (or I can anticipate a cut-out) I throw it into neutral and the truck keeps running.

 

I have read several dozen of posts here and I know it could be anything that I am willing to throw $$$ into replacing.  I am have done all the  work myself: tune-up, fuel filter, cleaned the throttle body, cleaned one ground on the firewall.  I am not the greatest of mechanics, but I do love this truck.  I would also love to drive this truck without worry of an accident from a stall.  I am hoping this neutral observation will help identify the issue, as it is somewhat unique to what I have seen posted from other CC users.  Thanks very much.

Do aLL the grounds. And, check to see if the engine to trans bolts might be loose.

Movement between engine and trans, causing the interruption of the CPS signal.

To whom it may concern , I had a new 86' Comanche in my youth and after two years of driving it beyond limits off road .I had the same exact problem too a tee, and after paying the dealer $1,500.oo   to diagnosis from front to rear it ended up being that the fuel tank baffle came loose and created a hair line crack in the fuel pump and the motor was starving for fuel. I repl. them both myself for about $400 bucks at the time and the problem went away. ​I hope..... this helps....

Hi Jeeper.  Your retell about your 86 Comanche going beyond limits off-road makes me jealous!!  If I had the fuel pump replaced already would that make any difference?  No, correct, because they would not have replaced the fuel tank baffle?  I have to look up what that means.  The stalling stopped completely after this?

 

I am glad you responded with this.  I am at a loss with any 1 of the 1,000 things (and endless $$$) the stalling problem could mean.
