We just installed an Autometer A/F meter, tapped into the wire going to pin 60 on the ecu. While cruising and holding a steady rpm the meter constantly sweeps from deep lean to deep rich. Is this normal? I'm just wondering because I used to have a Haltech A/F meter on my talon and the readings at a constant rpm would generally be between stoich and rich, the readings would move, but you could tell that the ecu was trying to compensate. The readings on the SVT tells me that it is either giving too much or not enough gas, little compensating going on. Also, the CEL is on (went on after ORP install), so we're wondering if perhaps the O2 is bad, perhaps throwing off our readings and giving the ecu bad info. Any input would be appreciated.
