97 454 won't run right. PLEASE HELP!!

Stock 98 LS1 is what I used. Theyre not hard to do, you just need to be careful not to break the mounting tabs when you take the injectors off the rail.

ive got about 2000 miles on my fiveo injectors, solved my starting problem and it runs smoother. also did the fpg, plugs, wires, new dui distributor and coil. at 202500 miles my distributor gear was shot, sharp as a knife. I plan on doing the timing chain soon as its also original.
