Also car cranks but sometimes takes 2 trys to start. I changed plugs wires and fuel filter. At stop it almost idles so low then when car is put in reverse it wants to stall it seems but doesnt.

Check for vacuum leaks between the MAf and throttle body. Cracked air hoses can result in rough idle and when shifted into reverse, movement of the engine can open up the cracks resulting in more vacuum leaks and engine running poorly.
