My SS is a 2004 model I have a missfire that is being caused by a bad Sparkplug wire. I plan on changing the wires and plugs soon. I want to put the best in it but not if it will not make a difference. My SS has long tube Headers, Cold Air intake, and was fitted with a FAST air fuel meter, the air fuel meter was stolen. I'm thinking about buying, 8 New NGK Iridium IX Spark Plugs TR5IX # 7397 and Taylor Cable 79614 409 Pro Race LS Truck Race Fit Ignition Wire Set I do not plan on racing it, i just want the truck to run right and last a long time. What do you think, or what do you have installed in yours?

Pictures of the FAST device in the truck. I will be honest i don't know what it is used for. Thank you here are the pictures of the fast device

Motor: I will take pictures of the F.A.S.T Monitor this after noon.

This is the rear of the SS. I am not sure if they removed the rear cladding an put the roll pan on it or if they cut it to look that way.

I need to get the suspension on the front fixed, ball joints, tie rod ends, shocks. I also have to find out where the noise under the hood is coming from. I believe it is the EVAP or Purge value. I keep getting a check engine light with codes 455 and 174. After that I want to take it to the track and get a baseline to see where I am before modding. Right now it has long tube headers coldair intake, shaved tailgate and shaved high mounted break light. the exhaust tail pipe stops and points down right behind the cab. I think I want to go all the way back with the tailpipes to quite it down a little. i think it has a exhaust leak too.

yes i bought it from Bob Moore Buick on NW Expressway. No it is not supercharged, if it was they took it off.

Yes sir at Bob Moore
