Hey all im new here. Im recently out of the army (infantry) and now all seems crappy. My baby 2000 f150 5.4 4x4 has lost its *****. It drives fine but seems to lack power. It will get up to speed but is very slow at doing so. No passing power for high way, no 4x4 power to actually hit the trail, I loose speed going up hill and struggle to keep same speed, tires will not break loose and just seems to have lost lots of power and accel and tourqe. Problem is as such yet I dont have a single code at all, it starys fine runs fine (minus power) but I drive my buddies his to is all stock and it moves.... mine I hit the gas and it takes a minute then just slowly moves.... but new plugs motorcraft gaped and done right, coils are fine all filters fluids fine, cat is fine all sensores are clean.... perfect maticulous care and maint. Done. She has 190k on her so I need the help. I love this truck what can I do to restore power.... anyone in the el paso area as well....
