Sam,
I just bought new injectors for my VP 5.0 GXI Here:
$180 for a set of 8. Working well so far. Your's will probably be different, but this place should have them. Shop in Florida.

I had the same problem just last week. 2005 Bryant 200 / VP 5.0 GXI. I pulled all the spark plugs and found #2 & #6 plugs were fouled badly. I checked the plugs and they were working fine, so my mechanic and I determined that it was a fuel delivery problem. The fuel pump was replaced last...
