Well the high idle came back. No change when MAF harness pulled. Replaced with new MAF and car now idles around 800-850 neutral warm and a bit low in gear around 550-575. Should the idle be a bit higher. I'm guessing this is all controlled by the computer. Do I maybe have a lazy idle control valve. No stumbling on deceleration. The idle is low so it is a tad lumpy. No hesitation from idle when accelerating either. Need I keep looking or is this within the "norm."
