Hi everyone. I'm new to this forum and just wanted to see if anyone could give me advice about a problem i'm having with my 1999 SVT Cobra. I just finished having the engine rebuilt and i'm running 12lbs pounds of boost on an aftermarket supercharger. My problem is when I run the car with the radio going, head lights on and air conditioning it seems to want to stall out. When i'm coming to a stop and I shift into neutral the rpm's will sometimes drop to low and the car will stall out. Does anyone have an idea what could be causing this? I was told it could be do to the engine load when running the ac, radio, and headlights at the same time.

 

Welcome to the group. Post your question in the tech section.

 

I'd make sure your alternator isn't going bad. Take it to a parts store and they'll check it for free, along with the battery. Why not, it's free. If it's not putting out enough charge, you might have to get a new alternator, along with an Optima battery. Don't know if it's the problem, but get it checked out anyway.

 

my friends haveing the same problem with the engin that he just bilt. send it back to the place that re-bilt it for you and have it cheacked it might be a problem with the computer or just a bad altanator or batery it can be alot of differant things
