99 montero sport w/3.0. Car runs fine until it reaches 151 degrees, then it will barely run at all, unless you unplug the mass airflow sensor(MAF). Battery was replaced and hooked up backwards which is what started this mess. Any ideas would be appreciate When it starts running bad, it leans out according to the oxygen sensor readings and fuel trim.
