2004 Rx8 Automatic with 52k miles on it. The issues is when under load (say 50-100% throttle while driving, not idle) the car feels like it cuts out and hits a wall and then very slowly begins to accelerate smoothly. No idle or hesitation issues.
Just had diagnostic done for $120 to pull codes 441, 442, 446, and 2401 and stopped right there as the technician was not familiar with Rotaries. He confirmed coils and catalytic converter was operating normally.
I had a bunch of U codes like U0073, U0101 and U0155 but after searching it turns out those do not affect modules or vehicle operations and could be caused by my recent battery swap and loose cables
So according to my search, these codes 441, 442, 446, and 2401 deal with EVAP system
P0441 Evap System Incorrect Purge Flow
P0442 EVAP system lead detection (small leak)
P0446 EVAP system vent control circuit problem
P2401 EVAP system leak detection pump control circuit low
I printed a list of checks for these issues as well and will hand them to the dealer but I just wanted to see if someone had this 4k brick wall issue before and what their fix was.
Thanks
