Hello I dirve a 1994 ls400. I was coming home from work about two days ago and out of no where it missed real bad almost like a stall but didnt turn off. The whole way home it was missing and just had no power when i come to a stop it idles real low, and when i give it gas it acts like it doesnt want to go. What do yall think it could be? I tried putting a maf from another working ls and nothing. I checked the wires and plugs and there all good. I have no clue what might be causing this problem. Any help would be great.
