Shane,
I never did mess with the Crankshaft Position Sensor. That is probably THE
only stock sensor on my truck actually; currently at 138,000 miles too. I
think I am going to pick one up tomorrow and install it when I get home from
work. It looks like it will be a 15 minutes job.......hopefully. It is late,
I will just smirk and let that redneck joke pass.......this time! :)
