91 Rodeo running fine, but suddenly started using way to much gas. No error codes stored in computer. Idle is OK but when driving acts like it's floored half the time. Lots of power but no mileage! Any thoughts? Thanks, BC

replace your oxygen sensor. when your O2 sensor starts to crap out, it gives less and less accurate readings, causing the ECU to dump more and more fuel into the engine.
