I know there have been numerous post about people with their dash or headlights dimming but my case seems to be different than any of the others.
Every single time the RPMs hit 1500 when coming to a stop the lights will dim and if the heater is on high it sounds like I cut it down to like the second notch. But after it gets to 750 at idle they light back up like normal.
Also if I take the car up to 5k or higher and shift out the dash and headlights just start going crazy...they'll dim, light back up back and forth all the way down to idle. They only start doing that as soon as the clutch is pushed in. If I just leave it in gear at 5k+ the lights look like normal, its just when I push the clutch in. I'm clueless. Unysis12 (Phillip) has helped alot trying to figure out this problem but neither one of us are sure as to what is wrong.
BTW, its a 99 SVT 55k miles. I dont think any of my mods would make it do this, the only ones that might have an effect is the KKM and DMD.
I know I need new spark plugs and wires...they are going in next weekend.
I dont know, any ideas???
