It's seem like the code is air flow sensor range performance, i had change the new one air-flow and throttle body but still can't fix the code, when i driving til 120 deceleration braking appear that engine check light, how could i going to fix the code p0101, any help ?
P0101 ISUZU - Mass Air Flow Circuit Performancehttp://engine-codes.com/p0101_isuzu.htmlForum CodePossible causes- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor
Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor

Your SUV is really giving you a hard time, lol. Sorry but I've had those days too.
I would try to check if you have blocked EGR passages. If ok check for restricted MAP sensor vacuum hose/passage or restricted exhaust. I know you replaced the CAT but if the muffler is blocked then there would still be a restriction. Also check the wiring and connection to the MAP sensor.

Do you know the OBDII codes? I just had to replace my Mass Air Flow sensor, it seems to have fixed my problems. But check the error codes.
SOURCE: hi i have a fault code of p0101 on my isuzu
Mass air flow sensor error. Try spraying the sensor with mass air flow sensor cleaner(AND ONLY MAF CLEANER) and see if it clears up. if not you may be looking into a new mass air flow sensor. It should be located in the tube that goes to the air filter box.
