So this morning I was under my hood cleaning my engine and air filter and i noticed what sounded like a vacuum leak, so I start tracing lines seeing if theres any noticable air leakage. Nothing.... I dig deeper and notice on the rear of my iac is a steel looking "cap" and thats where the air is comming out of, is there some kind of blow off valve in the iac? Its a brand new motorcraft part i put on about a month ago, just after I did the throttle body hang fix, or could the tb hang fix cause a seal to blow? When cold my car doesnt have a steady idle, and it will stall that all started after the tb fix but I figured capping the line that feeds the iac would cause a wierd idle, so did I mess up my iac or is that how it is??
