So about 2 weeks ago I started having a idle problem. It would drop to about 400-500 rpm and just sit there. It would usually do it constantly but occasionaly it would idle normally which for me is about 1k. Also while this is going on my oil pressure drops to about 20 then stabilizes with gas. About a week later my fuel warning light came on and stayed on for a few days then turned off. Then about 2 days ago the car actually died while I had to clutch in and backing up it has done that about 4 times now. All I have done so far was reset my tps. I was playing on replacing plugs/wires next but I have to do some brake work first. Any ideas would be appreciated.

car info is in my sig

 

kind of a update but today when i turned on my headlights the car boggged down and tried to die

I had the alternator tested a few months back and it was perfect
