Long Crank (like more than 7 seconds) and random misfire
Anyone ever encounter this? Once in a blue moon, ill have random misfire when coming to a stop. The whole car shakes like 2 cylinders are dead. And then it goes away.
The other issue is long cranks. On a rare occasion, the car will crank for about 7 seconds before it hesitates to fire up. I never really cared much, but today, I decided to care and ask you guys. Normally, it fires up after about a second.
I have changed the plugs 5k miles ago, new battery recently, new rear O2 sensors about 5k miles ago, new air filter, and changed fuel brands to see if it was a bad batch of fuel. 52K miles on my 2012 ISF. No codes.

yeah ive tried fuel system cleaner. Maybe I'll try bg44. Thanks.
If not, I'll just pull the injectors and get them flow tested and cleaned.
