If anyone has any thoughts or ideas about this problem, I'd love to

Thanks in advance.
Re: Reduced Engine Power (2003 Suburban)
I had the same problem this month(2003yukon) it happens 3 times to me i
went to the dealer and they said : this problem because I modified the
lights from halogen to xenon they told me you have to remove the xenon

any electrical modification u have to remove it.
