Hey there. I have 2003 Ford Expedition XLT. Several days ago the service engine lights illuminated, I used my OBD Scanner and it reads P1507 Code. I thought it might be an IAC problem. I bought replacement and get it installed. However I noticed that the electrical connection is located on the bottom, instead of the side like on the OEM. Soon I discovered I bought the 5.4 version for my 4.6 Expedition. But the engine still works, haven't got code so far.
Should I buy the 4.6 version or make do with this one?
