Imrc module
I have a 1998 Ford f150 xlt 4.2 and I put a
new motor in it and used my old in take
upper and lower and every thing else is new
and after about 3200 miles it popped a code
p1537 and p1538 saying imrc were stuck
open so I pulled intake off checked the imrc
modules the bank one was not working at
all so I put ba New one in and it went out in
two days . For some reason the diaphragm
is getting damaged . I also put the truck on
my scanner and it showed only .4 volts to
one of the modules what would be causing
me these two problems.
