Choking/sputtering After headers install
A little background: have a 04 V6 mustang, has a few small bolt on upgrades, exhaust system, and intake, and just recently bbk shorty headers.
The issue is after the headers were installed I immediately noticed a chugging or choking as it accelerated.. I took it to an exhaust shop and they told me the headers weren't leaking but we did notice the rubber plug missing on my intake tube. Replacing the plug didn't fix the issue.
Any ideas? I'm fairly certain it's airflow it feels as if the engine isn't catching it all. It was fine before the header install spark plugs, wires and coils are all good.
