91 Z not firing on no. 1 cylinder. - ZR-1 Net Registry Forums

Hope someone can help. Last weekend took the Z out for the first time this year, been sitting in my cold garage all winter with stabil in the fuel. About 25 miles from home the engine started running rough. Even when I floored it it still was missing. Once home I started pulling spark plug wires and found #1 cylinder was dead. Pulled the sparkplug it seemed ok however the gap was about 45 thou. Regapped the plug still no difference however I am getting spark to that plug. I suspect the injectors. Last year I had the primary injectors tested everyone was between 12 & 13.6 except # 1 which was 6.3.
Since there is no one around here who knows how to work on the LT5, I have decided to pull the plenum myself and change the injectors. Here is where I need help. Gaskets, injectors, and what ever else I will need.
Who do I call for these items? I have decided on accel injectors as they are the best price. I also want to change the spark plug wires (red) there are bosch grey ones on the engine now.
