4th, at 2000 rpm only while lockup. Yeah. Plugs and wires changed. Only surges at 2000. kick it into a higher gear and it takes off. So, at WOT, as the computer ignores the sensors, it runs great.
It seems as though SOME sensor is misreading and the computer adjusts to compensate, then readjusts when another sensor shows resulting reading and then all over again. Makes sense because it'* a steady, rhythmic surge.
Oh, and I disconnected the AIT sensor and it ran fine...replaced with new and it still surges.
But what sensor is it? that'* the Q.
