Good morning. I have an 04 430 with 90k on it. Ran perfectly (except couldn't get trans to change to sport from comfort)until yesterday when I accelerated hard from a dead stop to enter traffic went maybe 30 yards and began to let off the accelerator a complete loss of power and the car went into limp home mode. I pulled off the highway. Read the engine code(s) and retrieved P0101 mass and a TPS/pedal position pending. Cleared stored codes and the check engine light is out. I can drive the car but there is no acceleration off the line but I can drive it if I accelerate slowly until it gains a little speed then accelerates normally and shifts correctly. It is not downshifting correctly and up shifts I have to hit the pedal more than. Quarter travel and then very quickly to get a down shift then most times it downshifts 2 gears. The check engine light is still off with these symptoms although it has lit 2 more times after erasing codes. I know this is a long post but want to get in all of my observations. Thanks
