I posted about my stalling problem about two weeks ago. An intermittent stalling problem that usually happened on right-hand turns, it happened only once on a left-hand turn. I suspected the fuel pump ( the car has 155k) I unplugged the fuse for the in-tank pump and the main pump got louder indicating the in-tank pump was working. I thought it may have been getting weak so I changed the in-tank pump. Same problem. I looked at the FI relay and noticed tiny cracks at the solder joints. I resoldered all the joints. Problem went away....until last night on the way home from work. :( Well today I was playing around under the hood and touched the wire from the pickup sensor (I think it's called the crank position sensor, it's housed in the top of the bellhousing). When I moved the wire the car stalled. I repeated it several times. Apparently the connection at the sensor is weakening and when I go around turns centrifugal force was moving the long harness around (about 20" in length) causing the open condition.
Just thought I'd let you guys know, maybe it can help someone else in the future. :)
