Misfiring and stalling out

Lately I've been having issues none of us, even my part stores in the area, can figure out.

She had a check engine light blinking indicating a active code yet when put on computer no codes show only misfires nothing in the active states.

She acts as if she's losing power. Sometimes she even makes a violent jerk while driving without warning and during sporadic moments she'll also drop in RPMs and acts as if in hitting the gas and the brake until I let off the pedal for a moment and press down again. Kind of a stop and go motion, but it lasts only a few seconds and usually during the times I'm in between 2 and 3 going about 35-50MPH

When she's idling in Park if I have the air on for too long or heated seats active shell idles a bit high within a 900 to 1200. When she stalls, she has a hard time rolling over and once she does, she has a very violent jerk course through her before turning over at last.

I've replaced the oil pressure sensor; 02 sensors, both of them. The MAF sensor, air filter, all four spark plugs and two boots that seem warped and loose. Pulled the fuel injector and air manifold apart to be sure nothing was clogging or in it. Yet she still has the same issues. I checked the oil filter, and it was in great shape.

For a day after the O2 sensor where replaced she ran awesomely then started acting up again suddenly. She shows a flashing engine light yet still no active codes and I'm at my wits end, trying to figure out what else this could be. She's not slipping or even overheating and her moments she does this are random as heck. Some trips she won't even act up.

When she does these random temperaments, she will not go past 55 MPH and the cruise control cuts off completely even if I'm using it and will not come out of such state until I pull over and shut her off for a few minutes then carry on driving once again. Most times once I do this, she won't act out anymore and has no issues reaching past 60. She has stalled out on me in drive four times now after all these parts have been replaced.
Do you
have the same problem?

When the check engine light is flashing, that indicates the engine is at that time experiencing a misfire. What codes did you get? You indicated they were misfire codes which make sense to me.

Let me know what they are.

Take care,
