Rb25det Neo, Cold Start Issues

[evil1]

hi

when i start the car in the morning, it makes a weird buzzing noise from the motor, but eventually goes away once its warm.

At first i thought it was a belt but i lubed them up a bit but yeah still makes the noise.

also when this happens, the 'check engine' light(orange motor thing) comes on, also 'slip' and 'traction control off' is on.

it drives fun even with the lights on. after a while after i turn it off then on again the lights turn off and the noise is gone.

any ideas on what this could be???

any help would be much appreciated

Thanks
