To start with had the car tuned on e85 at boosting performance in Illinois a few months after moved down to Florida after 2 or 3 drives the car started throwing p0171 bank one lean change out the front o2 sensor then got code p0134 bank one inactive. Replaced with the original o2 sensor still getting code p0134. Checked ground check Voltage check both fuse number 8s no vacuum leaks no exhaust leaks no boost leaks. 40 psi on fuel pressure. I'm at a lost. Is there anything I'm missing. Or could it just be as simple at a new tune due to the climate change the car is in.
