My vette has 90,000 miles on it and it still has the factory O2 sensors. My gas milage has been getting worse over the last 6 months. Would installing new sensors help with the gas milage or maybe even performance? The car is not running quite ad strong as it was. I have already done just about a complete tune-up including a new fuel filter and pcv filter. Thanks in advance, Paul :steering:
