Hi there guys and gals! I am from San Fran Bay but moved to Florida a few years ago. My mother just moved here and is having problems with her 2002 Expedition. It has 19000 confirmed miles and was bought new. After about 30 miles it sputters and the cats pop and it dies. It will restart and rev high but wont idle and dies again. We have had it checked at the dealer and they want a fortune (about what it's worth) to fix it. It has a 5.4. the dealer said it was the #1 coil and boots and needed plugs and the pcv hose was collapsing. We did the coil and a fuel filter and pcv and pulled the pcv line to check it and it's fine. I checked the EGR and if I apply vacuum to it while its running it mimicks the issue perfectly. Any help here would get my uncle to his doctor appts. Thank in advance. Oh and she wants to give this Truck to me and move back to Cali. So I am looking forward to being a happy Ford owner someday soon.
