lots of issues!

My 2000 GP GT keeps stalling, but then after i limp home and shut it off for an hour, it runs fine again. I have codes p0442, p1860 and p0102, I do have a exhaust leak so i'm not sure if thats causing issues. I unplugged the MAF but it made no difference. I also know i have and issue with the TCC solenoid, but would this cause stalling at low speeds?

Those three codes are unrelated, and are seperate problems....

If that exhaust leak is before the pre O2 sensor, that can screw up MAF readings, and also force the engine to run rich.....

Well with my mothers car had the same problem basically. And it has a exhaust leak. Has before and after fix, It was in a few shops and had tons of money thrown in to it...It kept throwing up the MAF sensor code. After replacing like 2 sensors. My brother put his MAP sensor off his car on to my mothers car. And it ran perfectly. Replaced the sensor and no more problems with that
