Default Rough Running, Idle Dropping

First post on here. I have an 01 Z06. Mods are Halltech CAI, Long tubes, X pipe and Borla straight pipes. No catalytic converters. Had it street tuned about 5 months ago. Just recently started running rough like it’s misfiring but all plugs and wires are good. Not throwing a misfire code. The idle has started dropping real low, just replaced o2 sensors, cleaned the MAF and checked the vacuum line for leaks all looks good. Any ideas? Cause I’m all out.

OEM cam? I have to wonder about the "street tune" and who did it? Where are you located? You need to complete your profile. The more info provided, the more likely you'll get a better result in you quest for help.

Make sure you don't have any unmetered air entering after the MAF. I've had the coupler partially slip off in the past.

I had the same problem and found my intake gaskets were not sealing before and after!

Default Issue Solved

Was able to get get my car on a buddy’s lift, turns out the wiring to one of the o2 sensors somehow melted to the headers. So the o2 sensor wasn’t reading and the car was dumping fuel causing it to run rough.
Simple fix. Thank you all.
