Idling nice and normal at 900rpm, put it in reverse or any forward gear and it drops to 500rpm or 400rpm shutters a little then goes up to the proper idle and smoothes out... ?

 

The RPMs will fall a bit in R/D, but it shouldnt want to die when you place a load on the motor. Any more details?

 

-When I go to R Or D it feels as if it will stall then the rpms come back up and stabalize

-When driving (sometimes) giving it the gas off idle it feels as if someone is turning spark on and off (starts to go then sputters and feels like it will die, then starts to go again etc), then I give it more gas and it pulls away ok

-When it shifts to a low rpm 2000-lower it feels like it hits a dead area hard to explain but it doesnt sound as powerful until i give it more gas again (sometimes)

- when accelerating at 2000rpm or under in od while driving it does the same feeling as when trying to accelerate off idle (sometimes)

But if you push it to the floor it pulls HARD and shifts great..
