so im having this problem where all my lights are flickering both interior and exterior when its parked and driving but it seems to slow when im driving. Any ideas on what the problem might be or has anyone encountered this before. I have recently replaced the battery and alternator. Im thinking its a bad ground from the alternator, but whats everyone elses thoughts on this. btw it has an automatic start if that might cause problems to i dont know

 

Sounds to me like a grounding issue. Good luck.
