    Default Issue started and can't fix.

    I was driving to a show 70 miles away when I went to pass a vehicle. I accelerated a little to get past and noticed when I backed down exhaust sounded funny and feels like it's sputtering. I just installed my Sniper EFI and a MSD Billet Distributor prior to going to this show. It was running fine up that point now feels under power on acceleration, but idles just fine & smooth. Tried to attach a datalog on here, but guess I don't know what or how to do it.

    Ensure the ignition timing is still synchronized (if ECU controlled timing), and inspect the internal distributor components.

    Ignition is not controlled through ECU.

    One thing I just thought of, I zipped tied the WBO2 sensor wire to the battery wire of my starter to keep it away from exhaust. I think I'll isolate the wire from everything. Also going to pull the plugs to see how they look. I'm running a 350SP/385 crate engine with a Aeromotive Phantom 340 https://aeromotiveinc.com/product/ph...h-fuel-system/ in-tank fuel pump, and don't know if I should check mild cam or street/strip?
