I installed a Pertronix ignition module and 0.6 ohm Flamethrower coil on the 292 engine in my TBird (6 volt still) along with all new plug wires. It runs fine...maybe could use a small timing adjustment for slight initial hesitation when accelerating...but other wise good. Since I've made this change, it seems that once the engine warms up it "boggs down" at approx 2000 rpm (45-50 mph). The engine runs rough and lacks power. The problem doesn't exist right after start up. Though it acts somewhat like it may not be getting enough fuel, I also have a new fuel pump (and I can take it right past 2000 rpm to whatever speed right after startup). Could a bad coil be the problem. Any ideas what else to troubleshoot?
