I got my first jeep about 3 weeks ago. It's a 98 XJ SE 4.0 auto with about 114000 miles on it. I drove it from Chatanooga back down to Central Florida with no problems, but after about three weeks I have some issues.
In the last week or so I started to notice the motor missing occasionally between 40 and 50 mph. Now it has begun to stall out at least once a day when slowing down to a stop. After the motor dies the power steering goes, but I still have electrical power because the radio and air conditioner keep running.
I was thinking it might be a fuel pump or filter problem but I got it scanned for error codes at Advance and it turned up a P0320 code. The scan described the problem as an "Ignition/Dist Engine Speed Input Circut Malfunction". Thier computer says that I need to replace a Speed Sensor, specifically a $137.26 GP Sorensen model #779-9719. I have a picture of the part but have no idea where it goes, and I don't have a manual yet.
I have now spent a good amount of time looking for more info on the web and through naxja posts to get more info but I haven't seen anything that only addresses the P0320 code or that really focuses on this sensor being a problem.
It seems from what I have been reading that this could be one of several bad sensors, or a faulty wiring issue.
Anyone out there have this problem before. I am open to any new suggestions.
( I am also open to im's from anyone with tips on places to find a factory service manual online! )
