Checked the wiring and connections on the maf, and ect 1 and 2, all look good. Any

http://www.obd-codes.com/p0128 -- check this out for possible causes and solutions. Is your coolant level correct? Also could be a stuck open thermostat or cooling fans staying on to much at an idle.

I've checked that out. Like I said, I already replaced my thermostat and coolant. Fans are working correctly too.

Yes, short of replacing it. The wiring and harness look fine, no corrosion, etc.
