Car idles great, put in gear and begins the spit and sputter??

[griz_83ho]

Recently did a motor swap on a GN and having a issue. Motor starts and runs great but when you put it In drive the car starts off one but then starts spit and sputtering. If you hold the break it will sometimes idle fine and then sometime spit and sputter and almost die. I know some have said converter but when I drive the car low rpm seem to be fine, but when you accelerate it starts spit and sputtering a lot and will not accelerate.
I replaced the coil, ECM, injectors and chip, new plugs and wires. Also put a new tps sensor and its adjusted to .42.
Where would you guys go??

did you change the ignition control module?

Did not change ignition control module. Can swap it tonight one other thing is the service engine light is on

I don't think the engine light will lit if the ignition control is faulty,

See if you can get a code number and go from there.
