Just wondering if a faulty brain box can make the engine to be firing on its own irregularly, causing the rpm to be going up and down when not engaged but when it is engaged with my leg on the break pedal,the rpm comes down to the first mark thereby causing the engine not to steam normally.Also intermittently the car will fire itself and then becomes normal and then goes back to steam irregularly with the rpm dropping again.But when the car accelerate,it seems ok.

also The car jerks,shows a blinking engine malfunction signal,d fans were not rotating so so a wire relay was added.now we hear there is no need for that.what effect could the added relays have on d engine?

Refrigerant is ok.
Compressor is working good.
Compressor fails to cool, and I think the problem could be electrical.
Controls are ok too.
