check for deposits in the airhorn at the breather end

SOURCE: 2002 Jeep Grand Cherokee 4.0L Oil gauge reading very high

If the weather in your area is colder than normal, your startup oil pressure will reflect this, essentially because it is much thicker when very cold. This high reading should drop to "normal" once it reaches operating temperature. This condition can also be caused by a sticking pressure relief in the oil pump, usually caused by sludge inside the engine. If you regularly maintain your vehicle and use good quality oil, this should not happen. The oil pressure sending unit is also suspect, but in your case, I would not put it at the front of the list. If oil is close to "change time" consider using a good synthetic oil (synthetics flow better at extreme temps) or using a 5W anything oil during winter months. (see manufacturers specs)

I had the exact same problem on my 04 GC. I put some Techron Concentrate Plus Fuel System Cleaner in from Wal-Mart and it seemed to fix the problems right away. Let me know.
