Need some input on this issue.
Fluttering loss of power seems to occur at random RPMS. IMRC works perfect, opens when it's supposed to. New plugs, resistance tests fine across wires. EGR has been cleaned, and new controller unit installed.
New alternator, but does the headlight dimming.
So the power loss for example can occur during WOT, 4500k-5000k, smooth to 5500k, power loss from 5500 to 6000k, then smooth to redline. It is just small, but still very noticeable.
Someone give me some reasons to why this could happen. I don't believe the alternator is the problem , however that "voltage hunting" could very well be the reason.
Hopefully someone has seen this problem before.
Thanks in advance!
