(Thread Starter) |   Not Ranked : 0 score  Poor gas mileage from 260-280 miles on a tank down to 200-220 miles per tank? Does anyone else have some ideas as to why my gas mileage is so bad? I'm using the same gas i've always used which is 91 from QT. I'm still running the same map i've been on for several months. I'm just over 15,000 miles on my Denso ITV22s. I just did a MAF sensor cleaning and that did not resolve the problem. What else should I look at or could be causing this? Thanks Eric Sent from my Transformer TF101 using Tapatalk

| Not Ranked : 0 score a little bit of ethanol won't hurt gas mileage that bad. Full E85 won't hurt gas mileage that bad  How many miles are on the car? Can you grab an AP log of slow acceleration (like a MAF cal log) and a WOT log? |

(Thread Starter) | Not Ranked : 0 score I will grab some logs later this week and post them up. My tyranny mount needs to be replaced and the new one arrives Wednesday. My car just rolled over to 66,666 miles on Saturday. Also the poor gas mileage has been on several tanks in a row. Sent from my DROIDX using Tapatalk
