Hesitation While Accelerating from stop

[joezek]

My 98 explorer had a bad problem of stalling when turning left. It would only do it when the engine was hot, and only within the first 5 minutes after restarting a hot engine- like after running inside a fast food place or something. It would also do it if you drove at a slow speed of around 35 mph for long period of time, followed by stopping at a traffic light and then turning left.

Apparently Ford went through 7 or more design changes on the fuel pump pick up design because of this issue. If the tank was within 1/4 of being empty was when it acted up the most. We changed the pump and it still did it once in a while, but was much better.

We almost got killed in a head on accident with an 18 wheeler because it stalled 1/2 way across an intersection, and the 18 wheeler was coming down a bridge in the rain. I had figured out that if I power brake before turning left it would give me warning of whether it would stall or not. That was my safety measure, if it stalls so what I was still not rolling into traffic...This time however it let me all the way out into the road before stalling. Somehow I got it in neutral and restarted, and got out of the way just in time. When I looked in the rear view the 18 wheeler had already passed.

Mine never stalls it just hesitates. I changed the fuel filter and it seemed to fix it for a few days then it started up again maybe I have trash in my tank

Any new updates? Did you change the filter again and see what's in the old one?
