Hi everyone any help that can be provided would great.

Recently had to replace the CPS and that resolved the car stalling while driving, no stalls for several days after install, which beforehand, was a daily occurrence. However, tonight i was out driving and getting on the car a little.

I was at a full stop, laid into the throttle (full), the car got to about 4000 RPM and i lost all power to the rear wheels and the car stalled.

I braked put the car into neutral and restarted the engine no problems. Check Engine light is now on.

Tried this a couple times from a dead stop and same problem persisted.

Tried from a rolling start roughly 10 mph, full throttle, no stall but it did feel like the transmission missed the shift a little, felt like a hard shift.

Used the "manual" shift with the full throttle, stalled.

Used the "manual" shift with maybe 80% throttle and shifting a little early, no problems.
Used the automatic shift with maybe 80% throttle, still felt a little bit like a hard shift but didn't stall out.

Anyone have experience with anything like this?
