It could also be your VAF or ECT. Here's a link to the FSM pages of it: http://personal.utulsa.edu/~nathan-b...26diagnosi.pdf
How is your pickup running? Is there a noticeable loss of performance or hesitation?

Check the wire harness from the O2 sensor where it goes accross and under the exhaust pipe on the cross member. Mine was melted after comming in contact with the exhaust pipe.
