Just like the title says. I m completely stumped. Everytime I hit past like 4lbs of boost, My car starts stuttering and bucking. I pull the plug in cyl 1 and the gap is closed. I ve replaced the coilpack, the injector in cylinder 1, the ignitor, and the injector resistor. I have a Walbro 190 coming tommorrow, although upon testing, the pum is fine. Using a noid light, the inector is only seeing signal half the time? Also, after tying plastic bags tover all of the injectors, it is spraying, althoug I can be sure if it is when I hit boost. My laptop crashed, so I cant even datalog. Please help, I can hardly drive my car!
