Please help ,
I have 2002 df140 it started showing signs of faulty iac valve (hard starting, won't idle) luckily I have another running df140 that I swapped IAC's with. No results. Leading me to believe the ecm is not giving the IAC the signal to operate. So I then swapped ecm's with the other motor and the problem remained , after one attempt at cranking and realizing that the problem was not solved I but the ecm back in the other motor and to my horror the other motor started exhibiting the same symptoms. Some thing in the bad motor appears to be burning up ecm's instantaneously.. at $1500 a pop this is not a good problem to have. Has anyone ever experienced a similar issue?
