My 99 V6 has been doing this weird thing with its oil pressure. During the first 5 minutes of running the oil pressure gauge will drop to zero when I slow down or stop. If u rev the motor up it goes right back up to normal. After the car warms up a lil bit the gauge stays at normal all the time just as it should. Just had a fresh oil change bout a month and a half ago. Oil level is good. Has anyone else had this problem.

Funny....my 1989 does this same thing. At idle first thing in the morning it is fine, but after it warms up and you come to a stop the pressure falls to 0. Then when you barley give it gas, it comes right back up. Let off and it falls to 0. I replaced the Oil Sending Unit and it still does it!
I think it is a bearing going bad but the car does not use any oil regardless of how hard I beat on it

Are you serious? How do they go bad? This is my second Fox Body and my first one I only had long enough to do the interior and then I got rid of itOriginally posted by greenbullitt View Postcam bearings...itll die soon

One thing I forgot to mention was that the pressure stays constant when going down the road. Sometimes the gauge will sit there and bounce a few times when it is idling, but eventually it will go to 0 and stay there until I go to accelerate.Comment
