I pulled a MAF off of another vehicle and installed it. LTFT immediately improved to +8 to +15 range. Apparently the MAF was giving a reading, it just wasn't correct, no matter how much I cleaned it.
I have not even messed with it i do have a new dephi maf i need to install i just havent had the chance to yet
