Okay Imy check engine light has been on for quite a while. I got it diagnosed and possible causes were 02 sensors, engine repair, or vacuum hose/leak. My 94 suburban is riding great so I doubted the engine repair. Had one 02 sensor replaced and now the diagnostic is reading the other 02 sensor, and that's it. My question is if I replace the last 02 sensor, would my check engine light go off? Thanks
 
CHances are that your engine is NOT mixing air/fuel correctly. Have your throttle body and idle air control valve cleaned out to insure proper mix. Unburnt fuel burns out O2 sensore and exhuast systems quickly. Also, get rid of the factory plugs, and install Bosch Platinum or Nippondenso Iridium plugs. You will get more power, better gas mileage, and your emissions will drop. If you need the O2 sensors, stick with Bosch units. They are the ones that invented them!!!
