Just replaced engine in 05 sport trac (4.0 SOHC). Ran great for about 25 minutes then started hesitating and stalling bad then throwing p0320 code finally got to point wouldn't start unless allowed to sit for 20 minutes or so (hood open). Replaced ckp sensor seemed to have fixed it until about an hour of driving later. Doesn't die anymore but wont accelerate in gear below 1500RPM once above that range seems to do fine. Engine revs in neutral just fine but stumbles under a load. Can not duplicate symptoms unless running for 20 plus minutes. Plan on replacing wires from pcm to crank sensor tonight with a new pigtail at the sensor but want to know if anyone experienced this before. (Engine replaced due to timing chain guide failure)
have the same problem?
