they past couple of days my truck keeps stalling in gear after I let up off the pedal it does it warm or cold usually while steering or the ac is on is this normal?

 

Yes my 98.0 did at just under 200k. If it's like mine it would do it wether warm or cold. It would do it when I would tap the go pedal then release. I see you got a few miles on yours also.<br>A Cummins West guy told me why he thought it did and a possable fix.<br>He said that over time the injection pump throttle arm (on the back side of pump) wears out just enough to cause it to shut the fuel completely off for a split second on a hard return -then stall. He suggested to adjust the slack out of the linkage so it wouldn't &quot; over return &quot; &amp; to make sure the idle is set to the high side of the parameter.<br>I did &amp; been stall free ever since.<br>750-800 rpms in drive &amp; ac on for autos. Its a screw &amp; locknut on the rear of pump.<br>hope this helps <br>db

 

adjusted idle no more problems now thanks

 

I'll be doing this same fix this weekend. Thanks. 8)

 

had the same problem with mine and thats right. adjust the idol up and it will stop stalling
