Hola all, I got a 94, which is throwing codes 25 and 26 which is air fuel ratio being rich and lean at the same time, like w a t?? Any info on what could cause this, also at the same time the car is burning and I mean really burning through oil, I did a oil change maybe 1500-2000 miles ago and today it was empty

As far as your codes I would check for a vacuum leak at your hoses and check for a cracked intake tube and check the resistance on your O2 sensors. The FSM calls for 5.5-6 ohms.
As far as the oil I would check the front/rear main oil seals, oil pan gasket, etc.

Or your O2 sensors are done for because they're covered in vaporized oil that has collected on them and condensed.
