Review on Standard Motor Products PC169T Crankshaft by Nick Ward

I had an issue where my revs jumped 500-700 rpm higher on the highway and the jeep bounced for a second. This could happen if you drove at highway speed for about 20 minutes, and then about every 5 minutes. I removed the old one and cleaned the sensor surface and electrical connector and the problem seems to have gone away. I had a trip to Fordyce so I bought this and installed it for peace of mind. It has been running for a month now and has survived 2 river crossings and several hours of driving with no problems.
