Hello and welcome to Just answer,
This is a fairly simple replacement, Make sure the key is in the OFF position, Loosen the 2 hose clamps on each side then disconnect the electrical connector, slide the sensor from the two large hoses, reverse to install.
The sensor is located on the aircleaner cover as shown below
Simple Job all you need is a flathead screwdriver. There is just one MAF on your engine.
Click HERE for the diagram of the engine compartment, Notice the Arrow "A" in the diagram the MAF is just above this connected to the air cleaner.
Most Reman parts have a good warranty, and are acceptable replacements, I would consider using the reman for $80 since the price Gap is so wide, but nothing is better than Original equipment parts.
If you can go to www.acdelco.com and use their locater service and see if they have a retailer near your location, you can get the same one they are selling you at the dealer ship for around $175-200, which is a new one, they also offer their reman one for about $125.
The only problem with using the one from Oriellys is, if this doesn't fix the problem the delaer has a leg to stand on in saying that you used an aftermarket reman part. but for $200 difference I would take a shot at the reman.
If there are not any more problems the light will eventually go away on its on, it will take some time.
If you take the car by oriellys where you bought the part, they usually can clear the code with a reader free of charge.
Sorry for the delay and I see you found what you were looking for.
Thanks appreciate the accept and bonus money and the positive feedback.
Let me know if you have more questions
