Default car misfires only when cold any ideas?
When my engine is cold the car will start fine, but if i try moving, or applying gas, itll start mis firing. I pull codes, all the same, misfire random/intermittent on cyl 1 3 and 4..i switched the coil packs on 1 and 2, and i just had my ignition control unit, or ignition amp replaced, along with my fuel filter... when the car warms up, it runs great again...the check engine light will blink untill it starts to warm, then itll stabilize and stay lit...any help? im at my wits end with this thing...

Try injector cleaner, check/change spark plugs. Helped my cold misfire, but I'm non turbo.
