Have had problems with stalling lately. 2000 4X4 Ram Sport w/ 5.9l. The truck will stall while slowing down to stop or turn a corner. Also, while driving down the road, it will suddenly start to sound like it is misfiring, thus causing a CEL for misfire in cyl 5 and intermittent loss of CKP/CPS . I have periodic ABS and Brake lights. Funny thing is, after it warms up, seems to run fine. I've changed the plugs/wires/cap/roter and replaced the ASD relay, which seemed to improve the problem slightly. I'm thinking maybe the speed control sensor on the tranny. The dealer thought it was the alarm system and couldn't figure out why it wasn't letting them test the system, until they found out they forgot to disarm the system!!! Anyone got any other ideas???

 

Weak battery or bad alt could cause that. Mine stalled when I slowed down/let off the gas when my IAC was gunked up. Cleaned it and was good to go. Never seemed like it was misfiring because of the IAC though.
