Default Re: Help Needed

You have two sensors, one for the gauge with a single wire connector, and one for the pcm with a two wire connector, which is the one you want to change. They are both on the the driver's side of the head, just take off the intake air tube to gain access. This is always a good place start. You should also read any stored OBD1 codes and post them here.
Have you read this ?
