i have an early build 99 fps (built before 12/98) and recently experiencing rough idling. had and injector shop run diag on it and they said idm module was going. original idm is '110' - rcvd a rebuilt idm from internet which was a idm 120. called company purchased from, they said they are 'all' interchangable. my local ford parts store said they couldn't cross ref. the two part numbers-said the 'engineering' might be different on the two since my motor was early build. i installed the idm 120, still having issues with rough idle. clears up around 1200 rpm. anyone know about idm's?
would idm cause this issue? am i chasing the right culprit?:dunno: help. thanks!!
