Re: system lean codes
I am curious what you found as the final solution.
I had a situation where my LTFT was +25 both banks. Couldn't find any vac leaks. Checked live data and was getting believable readings from O2, MAP, and MAF. 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. |
