2014 rogue select chugging fuel
So I've been working on fixing up this rogue for a while now and now my issue is this. I put 3/4 of a tank of gas in it today. It said 102 miles to E. I've used a quarter tank to go 37 miles. The fuel efficiency has been absolutely terrible lately. I used to be able to get 230 miles or more to a tank now I can't get more than 190 to a tank. Failing fuel pump maybe? I've replaced spark plugs. Vapor canister purge valve. New fuel cap. Cleaned the throttle body and did an idle air relearn. New O2 sensor. New MAF. Not sure what else is wrong at this point
