Miss off Idle

When I rev my car up in park, I notice a few pops out the exhaust (like it stumbles) until it passes about 1500-2000 RPM's. This only happens if I really nail it. In Drive, it doesn't do this when you punch it or pull an overdrive load on it. Does this sound like the O2 sensor's or another issue? I have the delteq and my car runs great almost all the time, but when the motor is hot, I notice this one issue.

Do you think a cat could cause this. Mine started rattling the other day and now when I rev it, you can hear it poppin pretty hard. Plug wires are good and I think my coils are fine. Any help would be appreciated.

If it only does it in park I wouldn't worry about it, doesn't sound like any kind of serious issue.

just gut the cat and see if that fixes it. it shouldnt throw a code neither since its a 94. mine had the sames symptoms and that fixed it.

It's just annoying and I know its not right. It is only when it is hot too.

Thats what I wanna do. We don't have inspections here, but to stay safe i think I will gut it and put a straight pipe inside the cat housing.
