make sure your injectors are plugged in, in the correct order.

1: white, white/light green
2: black, white/red
3: white, red
4: yellow, white/light green
5: white, red
6: black, white/red

Is your check engine light on? Any code?

Codes

14 = ignition
24 = intake temp
31 = AFM Sig
34 = Turbo pressure sensor
52 = knock

Ive had a code 14 since i bought the car pretty much its annoying i think i need a new ECU. Ive swaped ignitors and new sparkplugs and wires and nothings changed
