In my 93 cougar, when im sitting at a stop light or something, my oil pressure drops down to nil, but if i put it in neutral or give er a little gas, it comes right back up and the light comes off. Checked the oil level, seemed alright, right below the full mark... any suggestions? i was thinking perhaps that the gauge is a piece.

I'd have a look at the following:

1. Find the oil pressure sending unit and take a look at it. If there appears to be oil leaking from it, replace it and you'll likeky solve the problem, as well as an oil leak :) They're not a particularly expensive part.

2. If everthing seems good here, pull the wire that goes to it and have a look. See if things are corroded and clean the connections as required. If the connections are severely corroded, this can cause a false reading and the oil light to illuminate.

3. Is the wire going to the sensor falling off? That will definitely cause your problem!

4. Again, inspect the the wire going to the sensor. Check for any obvious damage and repair.

If one of these steps don't solve your problem, it's probobly time to drop into your local Ford store and have them check your oil pressure with a gage. If it's not a sensor or an electrical problem, it might be oil pump replacement time.

Good Luck!!
