Hi,
My 1997 Silverado (1/2 ton 350) usually starts on the 1st turn of the key, but now it takes 4 or 5 times turning the key to get it to start and when it does start it runs a little rough for a few seconds, then cleans out and idles/runs fine.

The battery is ok and I just replaced the fuel filter hoping to correct this, but it still continues. Any advice/suggestions would be greatly appreciated.

Thanks,
gvw
