Yeah the older ones get really tricky.... The ECM'* were an improvement over the early versions.... But even they had a hard time telling you what the issues was untill it was too late...LOL... Been there several times... But my Crank sensor is still original... And after readign up on how they function I am tempted to replace them on both my LE and SE... The LE has been getting more and more quirky with its idle and low rpm operation...

Glad you got it running right... Now it should run good for a long time..

I believe thats air gap... There has to be a gap between both halves of the Hall effect sensor... I believe that its about .020 on either side
