Warm up problem

[C91BLX7]

Well its not really a problem, but I notice when the car is warming up (idle is still above 1krpm) It feels like the car misses randomly. Thats the only time it does it, its fine when it drops down to normal idle, and drives fine.

Not really a problem like I said, but I currently have some money to play with right now, so if its simple fix that could prevent me from problems farther down the road that would be great.

mine does it 2 on warmup, but idk. its kinda like a hiccup, doesnt bog or surge or anything, but something to noodle though

Have you ever replaced your O2 sensor? My H22A was doing that, but I started getting a CEL for the O2 so I replaced it, and it really smoothed out after that.

Its the original sensor far as I know, no codes.

I get that too and the RPM does not drop. Probably time for full intake manifold cleaning or EGR Port Service.

mine does the same except my idle drops a tiny bit.

i dont think its the o2 censor. i still get good gas mileage(28 to 30mpg)
