Was driving my 69 bird today, ~65 degrees out, car has been running great but had to stop short and ever since it has been sputtering at idle. I thought possible heat soak but the car has been running at a very good 180 degrees. Has a new fuel pump, plugs, wires, and has good to boarding high oil pressure. I plan on pulling the plugs as I think they may have gotten fouled due to the short stopping but was wondering if anyone has had a similar issue. Car is a 400 4pseed with an edlebrock 650 carb, just a street cruiser. Any help or insight is greatly appreciated
