I have just started the Head Gasket repair on my 2000 STS. I bought this car knowing it needed HG, so I have only driven it around the block, so to speak. Thus, not very much data on how it used to run. Also, this is my first experience owning/working on any Cadillac.
Following the FSM procedure, I got to taking off the air cleaner, and it said to disconnect the connector to the MAF/IAT. Not a problem, as it was already disconnected. The problem was that I can NOT find the connector that should have been plugged into the MAF. The MAF had these numbers on it: 1174512 & 25168491. The connector in the MAF has 5 male pins.
When taking out the PCM I found an unconnected plug laying beside the PCM, and had been routed there on purpose. This connector was purple in color, and was a 10-pin double row connector. The connector outline definitely did not match that on the MAF.
So, where is my MAF connector hiding?
Ideas are welcomed.
