I hope you guys can help me out. When I'm cruising around (2-3k rpms) it has a pretty steady miss to it. If I give it any thing more than half throttle, it goes away. It's a 93 Formula LT1 with a hotcam. Its got a new opti, new plug wires, and new icm. I was thinking maybe plugs, but would the miss go away when I got on it if it was plugs?

 

Its possible that the plugs may need to be changed. Another possiblity is th EGR system is malfunctioning.

 

i just solved my problem with a missfire around 2-3k rpms with a new mass airflow sensor and new ac delco O2 sensors. I dont know which one fixed it though.
