A few weeks ago my jeep would not turn over, it was dark, wet and snowing so I figured I'd hitchhike to work and try later. Later it would start then immediately stall out. Check light came on with P1391 (cam position sensor) and immediately light went off that same day. Two days later it started fine and I could hear the pcm correct the rough idle, so i figured I was out of the woods. Just a rough start and random miscode on a freezing wet morning, it happens...right! So I've been driving it now for almost a month and it always starts, drives great on downhills and flats but staggers and kind of jerks on up hills.I started simple and checked spark plugs, coils, air filter etc. all are awesome. Fuel filter is in tank and life time part on a 2000 so checked that off too. While looking into things I found that my water pump was weeping majorly. So we put in a new water pump in the rain...fun.
The hill staggering was not happening much until yesterday. Driving back up the pass from Reno is steep and my jeep was staggering most of the way. So now I'm finally excepting that I really have a sensor issue. Which is less than exciting as the cam sensor and the crank sensor look like hell to fix myself. I love working on my jeep but I think that I may have to draw the line at replacing the cam sensor, it seems over my head for my year (2000). What do ya'll think? Any thoughts or suggestions? Maybe I could get lucky and it might be the oxygen sensor!
