Been parked a long time. Before I went away a mechanic stopped working on it and it has been sitting for almost 5 years. Just prior to leaving a new Skunk2 IM was installed and would not start up when I tried. Stock throttle body still. Re routed some vacuum and coolant lines....running with a hunting idle. idles about 1200-1700 reving back and forth. Starts and sounds like it wants to smooth over but the immediately (cold) starts reving out. I am searching and trying a lot but not getting anywhere yet. Going to check for air leaks with tb cleaner today around the gaskets...no vacuum leaks. If the intake is removed and I cover the upper port in the throttle body I get a smooth idle. FITV? Foreign language to me on that do hickey. HELP PLEASE!! :bash
