I have a Isuzu Elf with the error code 52. I'm am not sure what it means. I'm looking for help. The gears are not shifting the way they should and once I get to third gear it goes back to neutral.

OK so I did the flashing code number and I got 99 But I don't see it on your list and I think it's a mass airflow problem

I keep getting a flash code 99. Truck acts like its in limp mode, hardly any power and shifts rough, however no black smoke to indicate a turbo blown. 50 mph max pull
