oil pressure low and rough idel
 

I was just setting in the parking lot it started to idel rough and I noticed the oil pressure was low all of a sudden and I just check it it was fine the fumes smelled real rich out of exhaust what's going on

Running rich, i would say O2 sensor. But the oil pressure makes me think otherwise....

If it was idling so rough that the motor rpm was dropping below 650 would explain the low oil pressure

Good point, in that case it could be the throttle position sensor too.

I was thinking the oil pump was failing or something
