Any advice for some positive STFT and LTFTs
Hey Scotty! 2010 Acura RL with 111K miles. I drive mostly in the city and was getting about 15.3 MPG in the summer, but now getting about 14.6MPG. Decided to see a live data using the scan tool and noticed STFT to be from +5 to 6% and LTFT +2 to 3% at idle. Clean new stock Honda filter, MAF was recently cleaned with CRC MAF cleaner. Throttle body is clean, all hoses seem to be soft, tight and in good shape. When I give it a bit of gas, STFT goes down some and may get closer to 0 and while driving LTFT may lower a bit too. I always use premium gas(tried different gas stations too) as it is required. Any ideas?
