92 LS400 rough idle and bogging
Hello gents. I just got a 92 LS400 from a friend recently. It had about a 1/4 tank of gas so i decided to run that out before I put i put new fuel inside. When the time came to refuel, i used premium and added a bottle of gas treatment. As soon as i pull off the car dies. After a few tries it cranks and enters "limp mode". So far I replaced the fuel filtet only. Wanted advice before I started throwing money at it. Also Im leaning towards it being a MAF problem because thats the code that came back and I unplugged it a little while ago and it started running a bit smoother but still no power really when I push the gas. Any help would be appreciated.

I drained all the old gas because i thought the same thing. (A full damn tank. Smh) and put in about a quarter tank of fresh gas and still the same thing.

I apologize for recommending to clean the MAF which is actually an AFM ( Air Flow Meter ) of the Karman Vortex kind which can't be cleaned. All you can try to do is spray some compressed air in there and hope it fixes it. I would look for a known good one on Ebay or somewhere else if it is in fact that part that is having issues. Maybe a junkyard.
