740 no power

Will have to look at the air cleaner also. Thanks. The regina system doesn't use an AMM per se but an air temperature sensor located in the same place. When it's unhooked it still runs but not at peak efficiency as the regina system uses ( if I understand which I may not) the air temp plus air pressure to figure the intake volume. I assume it's working on his car as the connection looks ok and there wasn't a fault code for it in the OBD box. I had an old 240 that the AMM went up on and I had to unplug to get it home and, like yours, it was running like crap w/o any power.

Many thanks!
