so i have jdm front that i didnt install (low inc. installed it) but whenever i put my headlights on (either the first click or second) my rpms go down just a tad and then up again like as if i put my ac on and then when i turn my lights off they go up and then down to the regular idle
i think it might be that, because my lights are drawing from the battery, its affects my rpm
has anyone come across this? is this bad for my engine? how do i fix it?
thanx for any help!
