You don't have a Fox Cougar so I can't offer any technical help. My guess would be to pull your codes and start from there.

i'm not sure what tps or iac means, but if you would care to explain i'm sure i could give you an answer. and yea checking the codes was my last option, casue i'd rather fix it myself then pay someone to fix it for me

TPS = Throttle position sensor
IAC = Idle air controller

Checking codes should be the first thing you do. So that you arn't throwing unneccesary parts at the car. You can go to Auto Zone or some place like that and have them check the codes for free.

A picture of your engine bay would be a great help.

hey guys got the answer to my question, with one of your suggestions, it ended up being a sending unit for the computer and a very very low in gear idle (400rpm)  so when stopped in gear the computer would think the car had no oil, due to very low rpm's which lowers the oil pressure, so an oil change and a new sending unit fixed this problem for me, thanks for the suggestions.
