when i bought the car, there was this 'power' light that would go on when i gave an extra push of gas, which would make the car take off nicely. i do not have turbo, well at least i dont think i do. now it rarely goes on when i floor it, maybe 2% of the time, and doesnt really help if it does, when i give gas now, the car just revs really high, and doesnt take off. any help????
