My 98 Wrangler quits sometimes when I slow for a light or I am just going slow in traffic. Today is quit but took about 20 minutes before it restarted. I started then I jumped out to shut the hood and it quit again. I cranked it and it sputtered some then started so I rev'd her up and zoomed down the road to the house. I checked the codes when I got home and the P0251 Code is showing. I replaced the ignition coil about 12 months ago and the CPS (Crank)about 14 months ago. Should I replace the Cam position sensor now? It is still starting but now I don't want to get stuck down the road. Any sugguestions ?
