Sometimes things like this can drive one nuts. And for the sake of
changing this part, that part and STILL not have the problem solved,
sometimes it's best to just "bite the bullet" and take it to the shop.
Been there, done that!
I assume you done the obivious and cleared the code after you
installed your new sensor. I just went though a problem with an 85
Chevrolet S-10 with a 2.5 engine. We replaceded the module in the
dist. with no luck and then after trying this that and the other it
came down to a hall affect sensor back in the the dist. Who would ever
think? Like I said things like this can really drive one nuts or in my
case NUTTIER.
Good luck and let us know what you end up finding out.
