When i turn on my headlights i lose power immediately and when i turn them off everything is back to normal. Also i have been having another issue since i bought the car some times when i start and drive my car i can not get the rpm's above 4000 in each gear the car won't let me go any faster but other times especially when it is warmer outside the car drives perfectly if anyone can tell me what is goin on i would really appreciate it.
