      I'm trying to prepare myself to rejoin the automotive workforce , being out of it for a while has really set me back and I was already behind on my electrical skills . so thank you for all of the video's that you produce .

    Thank you Sir for this great teaching. I was wondering what rpm should the calculated load should be 90% or more and if the calculated value is less that 90%, would the rear o2s oscillate rich lean?

    • @TSTseminars

      The rpm should be high and depends on the engine...the Calculated Load should be graphed and the vehicle should be driven from a stop at WOT (wide open throttle) be careful that they is nothing in front of the vehicle. This can be accomplished in a very short distance. If under 90% check for an intake restriction or even an exhaust restriction. The rear O2 should go up then g down after there is a steady rpm.Hope this answers your question. If you have not already subscribed to our tstseminars UA-cam channel please do so.
