Default help me diagnose this issue please

I just changed the plugs, wires, & air filter on my GF's automatic 94 LT1.

I runs pretty godd except now at idle it will try to run a little faster than normal idle (up to around 1000) and then it just drops for a fraction of a second (to about 400 rpm) and then runs normal.

This will repeat itself if you are at a long light or are just sitting at idle.

I removed the ASR box (throttle / cruise control?) to get to the odd side plugs but nothing else.

????
