Hello alm001,

i agree, this looks more like a fuel injector problem.

So i have some questions:
When did you clean the sparks the last time? / How many miles ago?

is your car a daily driver or a seasonal car or did it sit for a longer time in the past?

If is had sit for a longer time, did you use a fuel stabilizer before you got it to sleep?

Did you use an injection cleaner in the near past?

Was the engine really warmed up before you pulled the sparks? Because they should look a bit more brownish.

Thanks & regards,
Markus
