It has been over a year of expense and frustration. I have a beautiful, gleaming shining star of a goody but old-ie 1994 Jeep Wrangler. unk: I have just bought my 3rd Crank Shaft Sensor. I have been through the wringer with spark plugs and wires and distributor caps. (some saying they had to dry it off) I used to be able to go through the big puddles, now I baby it and am going on a hunt for real answers. From what I am reading when I google is a timing issue, or fuel pump. I am done with the crank sensor, and I figure I always seem to get answers here, so I registered. I hope I can get answers to keep my Jeep, Mine. My son-in-law, diesel mechanic, put the last crank shaft sensor on 5 days ago and it is starting to tug ( it is like a tugging feeling in the seat between 55 and 65 mph at over 3000 rpm ) again after driving 10 miles, so I think something to do with after warm up. I can not put it into 5th gear, it makes this clunking sound and a bigger tug of war. So I driver 25 miles in 4th at 55 to 60 with little tug. I hope there is someone out there, just like I, that sees the sun shining only on their jeep when they look at it a certain way and a sound of ahhhaaa while driving it that can help.
