i have had them replaced last year, would you think that the idm is bad.
also, what do p1219 (cid) mean, and where is the idm located on my 99 f-350 truck.
thanks alot
i was coming down the road and suddenly my truck started acting like it was missing. and finally i just pulled to the side of the road and put it in park and the truck sounded like it was running on 4 cyl.. no lights on dash but code -
po475-exhaust pressure control valve
p1219-cid...
