This is a bit annoying: My engine is misfiring badly at cold start. 2 shots of the accelerator pump and it will usually fire right up and go to high idle, but it misfires really badly initially. It runs around 1000 rpm due to the cylinders not firing (high idle is set to around 1500rpm). It takes a minute or so of running before all cylinders start firing and it idles fine then. While misfiring it smokes, is super rich and sounds terrible. I would like to get this sorted out since I want to drive the car regularly. My hunch is maybe the plugs are fouling until the engine warms up a bit or too cold heat range. I'm not too sure what to do about it... Anyone have another suggestion? Engine: 318, 8.6:1CR, stock heads, 340 stock cam, performer intake Carb: QFT SL-600-VS w/ electronic choke, mechanical pump Ignition: new MP orange box, MSD blaster 2 coil, new 8mm wires, proform dist 18°. E3 plugs. Vacuum at idle is about 16"
