I thought my ignitor was messed up, but I am sure now that it isn't. After putting on the ballast resistor for my msd coil and replacing my ignitor, my car still missfires. When I start my car up, it will idle rich and drive pretty rich also. After the motor warms up, and I am sitting at a stop light or stop sign, it will idle lean or stoich (this is according to the autometer air/fuel). The problems really start when I floor my car. It will do just fine until 5k and sometimes 6k rpm and it will missfire like crazy. This is at 9psi of boost. When the motor missfires the air/fuel gauge will bounce into stoich and then back to rich rapidly, but it doesnt bounce all the time, sometimes it will just stay in rich. And this missfire problem doesn't happen all the time, maybe 5% of the time it will pull all the way to 8k with no problems. I was wondering if clogged injector could cause this missfire. If it could be the injectors, how could I unclog them. Thanks.
