So I'm finally home and able to work on the car, it sporadically gave me trouble starting up before so i put in new coils yesterday. I replaced the spark plugs when i first got it a few months ago so they're basically new too. It starts up a lot better now but once i drive it after the warmup cycle is done it'll misfire a little. My boost gauge goes from -20 to around -15 for each pop to give some sort of scale. It doesn't happen a lot but it is noticable in the steering wheel when it happens. It seems to go away once the car is warmed up. Is it due to the cold or is the car just needing to acclimate to them? The old ones seemed really aged and worn. The new ones are OEM from fcp. They have like some white inner coating inside the boot when the old ones didn't. Anyone know what's up? I've put maybe 50 miles on the new coils.
