I bought a 98 LS1 out of a wreck that had sat for like a year, and when it started it missed and shook like crazy. I had a set of headers on it and I fired it up for a short period of time and then felt the headers (use a rag between your hand and the header) A couple of cylinders were very warm, a couple warm, and others dead cold. I put a noid light on each of the injectors and they were all getting pulsed, so I took the injectors off and took them to an injector service to be ultrasonically cleaned and flowed. Three or four of them were so gummed up they only flowed about half what they should of. About $150 later, with the injectors reinstalled the engine fired up and ran smoothly. Night and day difference.
The service I used said that injectors sitting for more than six months will deteriorate significantly if the fuel line is exposed to the atmospher and the rail allowed to dry out. (I'm in Arizona and the engine was out of Vegas, so it dries out quick)
Good luck

i had to cut the 2 back coil's harenss so i could relocate them on the firewall, cuase one was hitting the heaterbox and the other one was hitting the brake booster, so i whent back and dissconncted them and wired them back to stock length, but now the coli's was kinda just hanging down, and still even bringing them back to stock length didn't make any diffrents, i know its the 2 back coil plugs i cut cuase i can unplug them and the engine will start up but runs rough, plug them back in and still no diffrents. guess ill have to get anouther coil hanress or maybe the truck coils will work? i dont know oh well back to the drawing board
