I ran it for 2 minutes at 2000 RPM like the book said. But the gauge hadnt moved at al.

You should need to have the motor at operating temps before pulling codes. If the motor wasnt up to temp, it can spit an ECT code, and if the motor was real cold, it can spit a TAB/TAD code since the smog pump might still be diverting air flow to the heads, not the cats. Two mins should have been long enough to get the smog pump sending air to the cats, but who knows.............

Maybe try it again with a hot motor and see how it does (the ECT should be happy at about 180*F)

Good luck.

Tomm im going to run some codes, then if they are still not conclusive the HB is coming out and getting replaced.
