I have a 1993 ford f150 5L 4x4 with a AOD transmission. I am having a problem with my oild pressure dropping while I am driving it and if I get below a certain mph, using mph because I have no rpm gauge, the oil pressure is dropping to zero and the truck stalls. I just bought this truck and have taken the cataletic converter off becuase it was clogged, changed the oil and filter, changed the air filter and breather filter, new plugs and wires and new distributor cap. The firing order is correct and my timing should be just about right, I had to time by ear becasue the wife won't let me spend the money on a timing light. But it should be correct. I mean this is a 302 engine and beast of a machine and it should take a nuclear warhead to get it to stop. I think the last owner just didn't know what he was doing and messed a lot of stuff up and didn't take very good care of it, which is a shame becasue it is a beautiful truck. The other problem I am having is getting the four wheel drive to work but right now I am more concerned with getting the truck running and stay running before I mess with that. If anyone has any clues to what my problem might be I would grately appreciate the help. Thanks
