hey guys

i got an odd problem which i just cant figure out

just to get some stuff out of the way, my car drives fine during the day doesnt miss a beat, its rb25det with exhaust and pod bleed valve usual stuff everyones got runnin 10psi (in cefiro)

ok so day time is fine no headlights on (of course) but no matter what time of day or night when i turn on my headlights the car will drive fine then bog down real bad at random ! in all gears, say goin round a round about in 2nd n go to power out and it just splutters n makes all these really weird noises cant tell if its a missfire, feels like it though.. it will do it every now and then but without a doubt will do it at some point, off boost, coming onto boost or full boost will jerk around and stuff but turn off the lights and everything goes back to normal..

when you floor it on highway it will stuff around then stablilse but still doesnt feel strong

i want to upgrade to HID lights but want to get this out of the way first...

i dont understand how the headlights would affect the performance of my car, my turbo timer in volts mode always reads 12.3+ at the extreme lowest and boost gauge reads 18-20vac when off throttle..

if anyone has any ideas or sugestions that would be great

im gettin sick of avoiding driving at night but thats my fav time !!

thanks

try checking all the earths. sounds like the lights are robbing power from the ignition when you turn them on. stupid question maybe but if you turn the lights on during the day does it still play up?

You have an electrical issue somewhere.

Poor connection, earths etc.

You really need to find someone who is an auto elec to track this stuff down if your not handy like that.

pull your speedo cluster out and check the ignition earth wire its a pink wire

if this burt out it will do what your talking of

this earth is easily damaged whilst installin stereos etc

thanks guys for the info, should any auto elec be able to sort this out?

and yeh if the lights are on during day it will play up..

i know i enough about the stuff to check earths n that but not much more..

does mobile auto elec cost heaps more than if i was to go in?

thanks

sussed out whole engine bay cant find any loose earths or any loose wires in general..

might spend few more days playin with it then try out auto elec

sounds like ur alternator might be on its way to the scrap bin get a multi meter put it on ur battery should show charge upwards of 12v then turn ur lights on if it drops below 12v then ur not gettin enough charge and u need to get ur alternator replaced
