so i changed my 4.0l v6 in my 07 mustang with an other 4.0 from a 05 mustang and since then i get limp mode and a bunch of error codes,p0102, p0108, p0135, p0155, p0581, p1000, p1489, p0496, p0138, p0455, p0406, u0172, b105d, b1028, b1403, b1353, c1501, c1502, c1503, c1504.

i checked all connections and grounds, everything seems ok except for the non existant catalytic converters, i have good voltage all accross for sensors, tb is almost brand new, replaced maf and cam shaft position sensor...
