I have had a rough idle since I bought it a month ago or so. I have replaced fuel lines, bulb, filters, VST filter, rebuilt the manual fuel pump, adjusted the idle timing to 8 degrees. What else could it be? I wanted to get the injectors cleaned but couldn't figure out how to remove them and the fuel rail.
