Intermittent problem...?
Car just started acting up 2 days ago.
Fine most of the time, then sounds like it misses or kind of a fluttering or resonance type sound from exhaust. Seems to do it mostly, or all at lower RPM's, mostly around 2k. Sounds louder and runs a little rough/jerky. It is not constant, comes and goes. Seems to do it more after I have sat at idle at a light etc. But if I give it some gas when it acts up, it powers right through it and then doesn't show any problem until cruising around again. Idles fine.
Ideas, things to check?

I was having similar problem with my 91 L98 forum member suggested I check injectors. found 2 bad ones. Called Jon @ Fuel Injector Connection 770-888-1662 ordered new injectors after installing them problem corrected.

I added some gas today, will see if that helps, maybe bad gas.

It was the O2 sensors. The problem became worse and I suspected these because I had them go out before. I didn't think it was the problem at first because had them replaced only 2.5-3 years ago. Plus have the heads/cam now and it is rougher and smells of fuel anyway.
