Engine stall

G'day guys,

Just installed a new petronix billet with the flame thrower 2 coil and now when stopping at lights or stop signs my car just drops out. Funny thing is its only at night.
Car won't start until I turn off my lights and window wipers then fires up straight away, though when slowing down again I have to turn off my wipers and or lights to get it back upto speed.

Could this be my coil?

I'm confused.

Any help would be great

Electronic ignitions like nearly all of your 12 volts. Mine will turn over quite fast but not fire. Put the battery charger on it for half hour and it starts right up. I would look to see how much power your alt or generator is putting out. Is the battery holding charge? Hope this helps
