My 96 MustangGT keeps sputtering, The voltage indicator keeps getting low when i turn on the electrical equipment. Here's are the things i have checked, alternator works fine, had a tune up in december, new battery, The only things that i havent checked are the fuel filter, battery cables, spark plug wires, and Ignition coil packs.

My car is not misfiring, it's not stalling out, idleing is fine, so is it a batch of gas, fuel filter, battery cables, spark plug wires, or ignition coil packs

 

ever change the fuel filter?

 

no, it that what the problem is?

 

no, is it that what the problem is?

 

how many miles you have? could be the fuel filter. changed spark plug wires recently?

 

71,000 miles, i haven't changed them because i got the car this past december, how do i know if they need to be changed?

 

Open the hood with the engine running and no light. If you see a lightning show, replace the wires. You could also try grabbing a wire with the engine running, but that can be a bit on the painful side.[:@]
