ok from all accounts what I was told was I was in need of a new computer.

My jeep has bogged down (RPM'S drop to 0) as if it is getting no fuel or air however all compression is good.

The jeep has had a misfire since I bought it. The jeep bogged down and jerked two years ago and sat in 2 different shops for 5 weeks and a computer was all they could come up with. We didn't change the computer then and drove fine for 2 years (50,000 miles) now all the sudden we are hopping again
We took it to another shop... again computer. we now have replaced the computer. At first things looked good.
Now however the jeep will just die out of no where. It also cranks with no fire if it wants to. The oil pressure drops but only when the jeep is hot and stopped say at a red light. The jumping and jerking returned yesterday so it seems as if changing the computer has added new problems.

Any suggestions? Any thing at all would be helpful and much appreciated.
I love my jeep and my husband's ready to drive it off a cliff.
