Been having some hesitant idle sometimes after starts. Always starts up immediately and strong., I noticed on my scan tool I have a couple counts of misfires and a couple cylinders, sometimes they alternate. But they do clear up, I do not have any codes.

I noticed the TPS is accurate sometimes, sometimes it shows 45% at full throttle, sometimes 99%

My mass airflow readings seem high under wide open throttle in the 300g/s sometimes

Sometimes, all of the O2 sensors go to 0 V under full throttle

I did have the fuel tank, fuel pump, and fuel filter replaced about three years ago because the car sat for a long time in the tank developed rust. They did not replace the fuel pump control unit which I believe was upgraded from 4 V to 5 V.

need some help from you guys. I know it’s not the coil packs or the transformer. Spark plugs are also good. Engine Bay pretty much looks brand new still
