SOURCE: I have a 1998 GMC
resistance in plug wires ... degrades them. I find this as a standard GMC Sierra problem. Two sets on mine already. Coding is for misfires. Also, possible to unplug your MAS [mass air sensor] which will keep the 'check engine' light on at all times but it will no longer be in the circuit and could also be another solution to the problem. Changing out O2 sensors is just expensive since there are Banks A and B and each bank has 2 sensors. The cost from a part store is 80$+... hate to know what they charge you at a garage.
Go with the new wire set first.

here is a link that might have the name of your part. and just a thought, instead of asking a GM dealer about the part just go to an auto body shop and get the name of your part. anyway here is the link http://www.autopartswarehouse.com/search/parts.php?N=10505+1623+4294963700&ddKeyword=

Don't know what size engine you have, look at your distributor cap, where # 1 is at, follow it to the spark plug, that's bank 1, sensor 1 will be right after the exhaust manifold on that side, but not pass the cat. converter.
