I have a 1999 F150 with a 5.4 V8 engine. The Service Engine Soon light recently came on and I had the computer code taken off at Autozone. The first time they told me that I needed a new EGR valve. The light then went off after a few times driving and I got the code checked again and a different person said I needed a new EGR sensor. While driving at a low speed with constant easy pressure on the accelarator it will hesitate and jump a bit. Which problem is most likely? If it is the EGR sensor, where is it located? Thanks.
